[AUCTeX-devel] TeXLive 2019 update broke preview-latex (was Re: Typeset LaTeX files with non-ascii file name in TeXLive 2018)

[Ikumi Keita]

Hi all,

It seems that the latest TeXLive 2019 update broke preview-latex.  I
quote a failure log of the latest pdflatex and a successful log of the
pdflatex with the latest update reverted, at the last of this message.

At first, I thought that it is only related with non-ascii file names,
but it turned out to be not so.  Just a plain file name of "abc.tex"
fails with the same error.

Is this common for others?  If so, I suspect that the change in the
internal of latex invalidated "\detokenize" that preview-latex uses to
input files with non-ascii names successfully.

I haven't tested other engines (xelatex and lualatex).

I'm afraid that we have to delay the release of AUCTeX 12.2, due to this
problem.

Regards,
Ikumi Keita
