Fragile LaTeX parsing in ReadBib

[EricEdwardBryant]

Hi there,

Parsing certain LaTex encoded Utf8 characters causes ReadBib to hang. This seems to really be a problem with tools::latexToUtf8, but perhaps a failsafe is in order?

# This works beautifully
library(RefManageR)
bib <- GetPubMedByID('19047157')
WriteBib(bib, 'example.bib')

# This will hang
result <- ReadBib('example.bib')

# because the following author fails in RefManageR:::ArrangeSingleAuthor
author <- "Mar{\\a'\\i}a A Balboa"
tools::latexToUtf8(tools::parseLatex(author))

Cheers,
Eric

Just encountered the same problem with the following name:

author <- "Abad, Mar{\\'\\i}a J. F."
tools::latexToUtf8(tools::parseLatex(author))
