I recently had to reformat my D: drive where MiKTeX was installed. I reinstalled MiKTeX, but now the project I was working on won't compile. I tried repairing, uninstalling, and reinstalling MiKTeX, but nothing worked. Finally, I uninstalled MiKTeX and installed TeXLive, but the issue persists.

When I try to run pdflatex, I get the error:

...
(d:/Program Files/texlive/2020/texmf-dist/tex/latex/biblatex/biblatex.sty
(d:/Program Files/texlive/2020/texmf-dist/tex/latex/logreq/logreq.sty
(d:/Program Files/texlive/2020/texmf-dist/tex/latex/logreq/logreq.def))
! Text line contains an invalid character.
l.2175      \bgroup\nohyphenation#1\egroup^^^
                                             ^200b}}

Texmaker shows that the issue is in the biblatex.sty file. Lines 2171-2175 from that file:

\ifundef\XeTeXrevision
  {\providerobustcmd*{\textnohyphenation}[1]{%
     \bgroup\nohyphenation#1\egroup}}
  {\providerobustcmd*{\textnohyphenation}[1]{%
     \bgroup\nohyphenation#1\egroup^^^^200b}}

I haven't edited this file.

If I type in R when pdflatex is paused, the compilation continues and the pdf is created without errors from what I can tell, so this is really just a convenience issue. I can't e.g. compile the project in Texmaker.

This is an unfortunate side effect of using the pdfx package.

A simpler example is

\documentclass{article}

\usepackage{pdfx}

\begin{document}

\iffalse

^^^^200b

\fi
\end{document}

You could make the catcode of character 30 normal (12) rather than invalid (15)

\documentclass{article}

\usepackage{pdfx}
\catcode30=12
\begin{document}

\iffalse

^^^^200b

\fi
\end{document}

This issue was also reported at the biblatex bugtracker (https://github.com/plk/biblatex/issues/1044) and should be resolved on the biblatex side in the upcoming biblatex release.

The workaround biblatex now uses to avoid the problem is to isolate the problematic ^^^^200b to a file that is only read by the Unicode engines, where it is apparently not disallowed by pdfx/\UseRawInputEncoding.

  • thanks for avoiding this in biblatex, pdflatex sees ^^^ as control-^ which is character 30 which pdfx makes invalid... – David Carlisle Oct 1 at 20:19
  • Well, it is not coding in pdfx that makes it invalid, but LaTeX coding from use of \UseRawInputEncoding . With a name like RawInputEncoding one would naturally think that all characters would be recognised, but that is not so, as many are set to catcode 15 = invalid. What then is the real purpose of \UseRawInputEncoding ? – Ross Moore Oct 2 at 0:03
  • @RossMoore As documented, it restores the catcode situation prior to the move to default-UTF8 in 2018. That means one treats files 'raw'. I'm very surprised it's used in pdfx: the command is for users processing older files that relied on undocumented behaviours (that parts of the upper half of the 8-bit range happened to work for some people without loading inputenc). – Joseph Wright Oct 2 at 6:57
  • @JosephWright. But it's lower bytes in the range < 32 that is the issue here. Many are made unavailable (catcode 15). How is that 'raw'? It's the name here that has led me to think this was appropriate, whatever version of LaTeX is being used. Clearly it is not, and I can program those catcodes to be reset after reading the .xmpdata file. – Ross Moore Oct 18 at 23:45
