I have encoded characters such as "\032\032\032\032\032\032\032\032" and I want to convert them to raw characters in R. How can this be done?

I read from a html file in R which contains Chinese characters. But it shows something like
" <td class=\"forumCell\">\xbbָ\xb4</td>"
It is the "\x" strings that I need to extract. How can I convert them into readable Chinese characters?
By the way, somehow simply copy and pasting the above \x strings would not replicate the problem.
are you sure they are all chinese characters? what is the html page encoding? the strings you pasted looks to be a mix of hex \xc4\xe3 and unicode chars \u0237.
Imported a bunch of CSV and one of the columns has what i think are Unicode chars.
something like:
PEÃ<U+0083>â<U+0080><U+0098>A
SOPEÃ<U+0083>â<U+0080><U+0098>A
Not in all rows, just some, but I've tried to convert to "human readable" chars but to no avail.
Tested this solution from SO but no success so far: unicode characters conversion in R
and this brute substitution didn't worked
gsub('Ã<U+0083>â<U+0080><U+0098>', 'Ñ', 'PEÃ<U+0083>â<U+0080><U+0098>A')
[1] "Ã<U+0083>â<U+0080><U+0098>"
I'm dealing with a text where I find UTF-16 encoded as UTF-8 and I am unable to translate from one to the other in the R language.
For example, and looking at this codepoint (https://codepoints.net/U+D83D) representation in UTF-8 as a text string "ED A0 BD" and I want to convert it to also a text string"D8 3D".
How can I achieve this?

I read in text from a MySQL table into and R dataframe. (using RODBC, sqlFetch). Have two questions:
How do I figure out if R has read it in as utf-8? It's character
type but what's the function to show encoding?
How do I compute the number of characters in an Unicode string in R?
The length function does not work with Unicode and always returns 1 I think.
You should be able to read the encoding (assuming it is specified) with:
Encoding(x)
The number of characters can be determined with:
nchar(x)
https://twitter.com/intent/tweet?source=webclient&text=G%C5
produces the following error:
Invalid Unicode value in one or more parameters
btw, that is the Å character
twitter expects parameters to be encoded as utf-8.
So Å is Unicode U+00C5, and represented as utf-8 is C3 85
With url-escape this means that the query should be ...&text=G%C3%85
Since I don't know how you are building that query (programming language/environment), I can't really tell you how to do it right. Only that you should convert your string to utf-8 before escaping.
