Re: [AUCTeX-devel] [AUCTeX] files with non-ascii characters and LaTeX as in TeXLive 2018

Hi Jean,

Thanks a lot again, the proposed method works on the command line!  I'll
implement it in the actual preview-latex code.

By the way, if I remember correctly, filenames with multiple contiguous
spaces are not supported by TeX, aren't they?  Standard pdflatex just
fails for such file names:
----------------------------------------------------------------------
[bash]$ cp ppp\ qqq.tex aaa\ \ bbb.tex
[bash]$ pdflatex aaa\ \ bbb.tex 
This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2018) (preloaded 
format=pdflatex)
 restricted \write18 enabled.
entering extended mode
! I can't find file `"aaa bbb.tex"'.
<*> "aaa  bbb.tex"
                  
(Press Enter to retry, or Control-D to exit)
Please type another input file name: 
----------------------------------------------------------------------
So I suppose that it is not necessary for preview-latex to support such
file names.
