There is what seems to be an encoding issue with UTF8, on my preproduction machine, that I cannot replicate on my development machine.
With the following FXML:
<Button fx:id="searchButton" defaultButton="true" text=" 🔍 Go !" />
Or with the following Java:
#FXML
private void initialize() {
...
searchButton.setText(" \ud83d\udd0d Go !");
...
}
I see the following on my development machine, both in Eclipse and with a exe native package
However, when running the native package (or even the JAR directly) on the production environment, I see the following If I change the code to searchButton.setText("\ud83d\udd0d");, I then see this:
As you can see, there is a strange square appearing, while the "🔍" shows properly.
It might be worth noting that the production machine is a Windows Server 2008 running 1.8.0_31 JRE, which motivated the packaging of the 1.8.0_101 from the development machine, into the native package.
What could be causing such a problem ?

I'm trying to build my Xamarin.Forms project and running into an unexpected error "'cxmlns' is an undeclared prefix. Line 3, position 14". I've tried searching the web for a solution to this but not fining any. I've seen other similar problems and I tried solutions that worked for others, but nothing that worked in my case so far. Here is my MainPage.xaml code:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
cxmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:DojoBoss"
x:Class="DojoBoss.MainPage"
BackgroundImage="background1">
</ContentPage>
I find it strange that I'm getting this error since this is all stock code that came with the blank app from Visual Studio (VS) aside from 1 line where I put in a background image. This was also working fine earlier today, I didn't make any changes but now it doesn't work. I've been disappointed with VS and Xamarin so far, seems very buggy and difficult to get started. Here's what I've tried so far:
Build project
Rebuild project
Clean project
Deselecting all projects from build (I have a main project + Android and Windows projects), applying changes, cleaning, building, re-selecting all projects to build multiple times in different orders.
Deleting bin and obj folders
Reopening VS multiple times
Deleting .vs folder, including the .suo file
Removing the line of code where error is thrown
Checking the build order
VS is also giving me 4 other errors which may be related to the problem:
Error CS0006 Metadata file 'C:\Users...\bin\Debug\netstandard2.0\DojoBoss.dll' could not be found
The "ResolveLibraryProjectImports" task failed unexpectedly.
Cannot resolve Assembly or Windows Metadata file 'C:\Users...\bin\Debug\netstandard2.0\DojoBoss.dll'
The name ‘InitializeComponent’ does not exist in the current context
I do not know what is this "cxmlns". Can we change this line
cxmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
to
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
I am testing google closure compiler on command line.
I took the latest version :
java -jar closure-compiler.jar --version
Closure Compiler (http://github.com/google/closure-compiler)
Version: v20190618
Built on: 2019-06-21 17:24
I am generating a compressed version of my javascript like this :
java -jar closure-compiler.jar my_script.js > out.js
The problem is that the generated code is bigger than the one I get when I use the online service at https://closure-compiler.appspot.com/home
I noticed that the command line version added, at the beginning, the following code :
var $jscomp=$jscomp||{};$jscomp.scope={};$jscomp.findInternal=function(a,c,b){a instanceof String&&(a=String(a));for(var d=a.length,e=0;e<d;e++){var f=a[e];if(c.call(b,f,e,a))return{i:e,v:f}}return{i:-1,v:void 0}};$jscomp.ASSUME_ES5=!1;$jscomp.ASSUME_NO_NATIVE_MAP=!1;$jscomp.ASSUME_NO_NATIVE_SET=!1;$jscomp.SIMPLE_FROUND_POLYFILL=!1;
$jscomp.defineProperty=$jscomp.ASSUME_ES5||"function"==typeof Object.defineProperties?Object.defineProperty:function(a,c,b){a!=Array.prototype&&a!=Object.prototype&&(a[c]=b.value)};$jscomp.getGlobal=function(a){return"undefined"!=typeof window&&window===a?a:"undefined"!=typeof global&&null!=global?global:a};$jscomp.global=$jscomp.getGlobal(this);
$jscomp.polyfill=function(a,c,b,d){if(c){b=$jscomp.global;a=a.split(".");for(d=0;d<a.length-1;d++){var e=a[d];e in b||(b[e]={});b=b[e]}a=a[a.length-1];d=b[a];c=c(d);c!=d&&null!=c&&$jscomp.defineProperty(b,a,{configurable:!0,writable:!0,value:c})}};$jscomp.polyfill("Array.prototype.find",function(a){return a?a:function(a,b){return $jscomp.findInternal(this,a,b).v}},"es6","es3");
I do not have such a code in my script: Where does it come from ?
how can I produce the same output as the online version ?
To get the compiler command line work as the web service, I just added an option :
--language_out=ECMASCRIPT_2015
This is likely a discrepancy between the settings on the web service and the ones you're using locally.
Have a look at a Closure Compiler: Flags and Options to see what settings you might prefer.
If you'd share your source, it'd be possible to try and help you narrow down the options.
As for the extra code, I believe it is at least partially a polyfill for Array.prototype.find (aka [].find), which I assume is in your code?
If so, that's Closure injecting code to improve your cross browser compatibility.
I have a problem using GoLand's debugger for a piece of code that tries to read from the stdin. For example, the following code:
package main
import (
"io"
"os"
"strings"
)
func main() {
io.Copy(os.Stdout, strings.NewReader("Start typing now...\n"))
io.Copy(os.Stdout, os.Stdin)
}
executes perfectly when I run it from within GoLand - the console window collects the input properly. But when I use the debug command - I can see the my input appearing in the console window, but the enter key will not end the input string, instead the cursor just moves to the next line.
My versions:
GoLand 2018.2.2
Build #GO-182.4129.57, built on August 23, 2018
JRE: 1.8.0_152-release-1248-b8 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.13.6
As you are using OSX there is no simple way to get this working.
Assuming you are using Go 1.10 or newer, change the directory to $GOPATH/src/github.com/user/package, then compile your application using go build -gcflags "all=-N -l" github.com/user/package, and then manually start the application in Terminal manually. Once the application runs, go to Run | Attach to Process... and select the application from the list. This will attach the debugger to the running application.
Please note that the compilation step is needed in order to improve the debugging experience but you should not use the resulting binary in production as (almost) all optimizations have been turned off.
I am installing opencpu on a new windows 10 box. It already runs on two other windows machines.
The library is found but opencpu is not recognized as an object, so the server does not start
> library(opencpu)
Loading config from C:/Users/jake_000/Documents/R/win-library/3.3/opencpu/config/defaults.conf
Loading config from C:\Users\jake_000\AppData\Local\opencpu\opencpu/user.conf
Welcome to OpenCPU!
> opencpu$start(9831)
Error: object 'opencpu' not found
Can anyone suggest what is going wrong here? Hopefully, this is basic human error, but I am at a loss.
It seems Jeroen has recently changed from using opencpu$start() to ocpu_start_server(). From the readme:
To start the single-user development server in R:
library(opencpu)
ocpu_start_server()
Or to start an App:
ocpu_start_app("rwebapps/stocks")
As to why you see different behavior between servers, my guess is you (or someone) did a devtools::install_github("opencpu/opencpu") more recently on one server than the other.
The last time I had my Windows Store app open (last night), I had a XAML error in it. I (tried to) open it tonight to try to fix it, but got all kinds of errors about things not being able to be loaded. Here are the important excerpts from the ActivityLog.xml file:

I shut VS down, reopened it and the project and, although I didn't see all those err msgs, and the project was ostensibly open, there was nothing in the Solution Explorer (no files displayed). I tried opening MainPage via File > Open, but that just resulted in another err msg.
The only other thing that changed the last time I had the project open was that I updated SQLite from version 3.8.7.1 to 3.8.7.2
What could be the solution (no pun intended)?
UPDATE
On trying to shut down Visual Studio, I got over and over again: "No exports were found that match the constraint...(bla bla bla)" until I had to stop it via Ctrl+Alt+Del
UPDATE 2
Here's what's even more bizarre: I can open the project and, although Solution Explorer is completely empty/no files
visible, if I build the project via Ctrl+Shift+B, it does give me the errors in the Error List (XAML errors in MainPage.xaml).
2-clicking them brings up nothing in the editor, though.
If I try to open MainPage.xaml, I get this:
But, although I just saved this file (the screen shot above), the date on it is 10/19/2014 - more than two months in the past. What the...?!?
What must I do to get this back to normal?
UPDATE 3
I do see this with the Team Explorer tab open (this app is not under version control):
Page '3185ed96-1cbd-4381-a439-636973542e50' not found.
I fixed the XAML issue by opening MainPage.xaml in Notepad ++ and changing the XAML around. I was then able to successfully build the app in Visual Studio, but trying to run the app caused VS to crash and then start up again (still with no files in Solution Explorer).
UPDATE 4
Now I get, "Package Designer Package failed to load" when I try to open MainPage.xaml via File > Open in VS 2013...
UPDATE 5
Now I can run the app (sort of); F5 causes the splash screen to display, and then it just goes gray-black. When I Alt+F4 to shut that down, VS starts back up again (apparently after shutting down - I intended to only shut down my running app, not Visual Studio.
AutoHistory tells me:
An exception was encountered while constructing the content of this frame. This information is also logged in "C:\Users\Clay\AppData\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml".

Anyway, I then notice that I do have a (literal) red flag, and mashing it shows me an "Renew your developer license" message.
I was able to update my dev license, but my solution is still wacky in the same ways as before.
UPDATE 6
Answering Walt Ritscher, I get this in AutoHistory on starting VS (no solution opened):
An exception was encountered while constructing the content of this frame. This information is also logged in "C:\Users\Clay\AppData\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml".

Then, when opening another project that was working fine the last time I had it open, it, too, shows no files in the Solution Explorer. If I try to run it, I get that same "No exports were found" err msg.
So VS itself is hosed, it seems. What need I do? Uninstall/reinstall?
It seems likely that your VS install is hosed. You can try a repair first, before doing a reinstall.
last week I have faced the similar problem with my Visual Studio . I think these problems occurs due to the Pc Cleaners/Pc problem fixer and others like that. I just reinstalled the windows and visual studio and the same code executed fine.
So VS itself is hosed, it seems. What need I do? Uninstall/reinstall?
I would definitely try that. However, first I would copy the project to another machine with VS installed and try there. If it works on another machine then there is a problem on the first machine, possibly VS, possibly some extension or add-in. If it doesn't work on another machine then there is a problem with the code.
