reading latex accents of .bib in R - r

Question

When I export .bib references with accents coded in latex (as they are exported from mendeley, for example), then they don't look as expected for further independent processing in R.
myfile.bib:
#misc{Llorens1980,
abstract = {Aunque el reactor de fusi{\'{o}}n termonuclear constituye la esperanza m{\'{a}}s s{\'{o}}lida de obtenci{\'{o}}n de energ{\'{i}}a a gran escala, los problemas f{\'{i}}sicos y tecnol{\'{o}}gicos que el mismo plantea son muchos y dif{\'{i}}ciles.},
author = {Llorens, Mart{\'{i}}n and Menzell, Alfred and Villarrubia, Miguel},
booktitle = {Investigaci{\'{o}}n y Ciencia (Scientific American)},
keywords = {INGENIER{\'{I}}A NUCLEAR},
number = {51},
pages = {1--5},
title = {{F{\'{i}}sica y tecnolog{\'{i}}a del reactor de fusi{\'{o}}n}},
volume = {DICIEMBRE},
year = {1980}
}
In R:
testbibR <- RefManageR::ReadBib("myfile.bib")
testbibR$author
[1] "Mart\\'in Llorens" "Alfred Menzell" "Miguel Villarrubia"
testbibR$title
[1] "{F{\\'{i}}sica y tecnolog{\\'{i}}a del reactor de fusi{\\'{o}}n}"
btex<-bibtex::read.bib("myfile.bib")
btex$author
[1] "Mart\\'in Llorens" "Alfred Menzell" "Miguel Villarrubia"
btex$title
[1] "{F{\\'{i}}sica y tecnolog{\\'{i}}a del reactor de fusi{\\'{o}}n}"
testbib <- bib2df::bib2df("myfile.bib")
testbib$AUTHOR[[1]]
[1] "Llorens, Mart{\\'{i}}n" "Menzell, Alfred" "Villarrubia, Miguel"
testbib$TITLE
[1] "F{\\'{i}}sica y tecnolog{\\'{i}}a del reactor de fusi{\\'{o}}n"
I wonder if I can see a Martín in those places

By the way, when importing / exporting those bibs, packages seem to rewrite in (other) latex format, the author field (Mart\'in). Only bib2df writes all fields as the original, see above.
RefManageR::WriteBib(testbibR,"refmanager.bib")
bibtex::write.bib(btex,"bibtex.bib")
bib2df::df2bib(testbib,"bib2df")

Answer 1

This is a workaround to remove some latex accents from .bib.
As I based this answer in this post' answer, the first part is in python.
python: Dictionary to .csv
latexAccents = [
[ u"Í", "{\\'{I}}"],
[ u"í", "{\\'{i}}"],
[ u"á", "{\\'{a}}"],
[ u"é", "{\\'{e}}"],
[ u"ó", "{\\'{o}}"],
[ u"ú", "{\\'{u}}"],
]
import pandas
mydf = pandas.DataFrame(latexAccents)
newname = "dictaccent.csv"
mydf.to_csv(newname, index =False)
R: Replace latex in .bib
dictaccent <- read.csv("dictaccent.csv")
bibLines <- readLines("myfile.bib")
library(stringi)
for (i in 1:nrow(dictaccent)){
for (j in 1:length(bibLines)) {
bibLines[j]<-stri_replace_all_fixed(bibLines[j], dictaccent$X1[i], dictaccent$X0[i])
}
}
writeLines(bibLines,"noLatex.bib")
