[AUCTeX-devel] Typeset LaTeX files with non-ascii file name in TeXLive 2018

[Ikumi Keita]

Hi developpers,

I'd like to commit a change proposed in
https://lists.gnu.org/archive/html/auctex/2018-05/msg00014.html
in order to resolve problems addressed in
https://lists.gnu.org/archive/html/auctex/2018-05/msg00003.html
https://lists.gnu.org/archive/html/auctex/2018-05/msg00004.html
.  Are there anyone who doesn't agree with this?

As explained in ealier messages, this patch introduces some
incompatibilities:
- Users cannot put raw TeX codes in the command line like
        latex -interaction=nonstopmode \SOME_CODE \input FILENAME
  via setting `TeX-command-extra-options' anymore, as long as the
  default `TeX-command-list' is used.
- (Pdf)latex binaries without e-TeX extension have the following two
  limitations:
  1. Preview-latex does not work.  (This can be circumvented by
     customizing `preview-LaTeX-command' and
     `preview-undump-replacements' to cancel the change by my patch,
     though)
  2. Region compilation (C-c C-r, C-c C-e etc.) does not work.
     I.e., such binaries can only use C-c C-c (and C-c C-a) to typeset
     the latex documents.
If you consider that these incompatibilities are not acceptable,
please express your opinion.  I would be ready to discuss about this.

If no objection, I'll commit the change in a few days.  Adding document
changes and regression tests will follow later.

Best regards,
Ikumi Keita

P.S.  I tested the patch with MikTeX briefly, and encountered no
errors.
