If nil, do not use \input, if not nil, use the \input with whatever extra measures are needed from the fact that any command will be executed after the format is loaded, hence the non-ascii characters assumed to be utf-8 and their first byte is active.Ah sorry for the confusion in this paragraph. In fact, the utf-8 first bytes are active in both cases, but in the case of pdflatex filename they have a temporary definition based on \string and the thing works For reference on this, these links http://tug.org/pipermail/tex-live/2018-May/041669.html https://github.com/latex3/latex2e/commit/93b375e40e3dbfd57093e5b527be1d357a942a99 indirectly explain it, because there was a problem on Windows that utf-8 filenames are presented to the binary in another encoding. The commit above contains modified definitions for the LaTeX address@hidden macros, but indirectly it does illustrate that the mechanism is in place already in pdflatex filename situation. The difference with pdflatex "\input" filename is that \input is processed at a later time and the LaTeX address@hidden macros have by then another meaning. I think.BestJean-François
Hi Keita, (sorry for having mixed-up firstname and lastname) A. In TeX-expand-list-builtin, there is in PDFout a possibility if variable TeX-DVI-via-PDFTeX is t that the command line will do \pdfoutput=0. This is a situation which would then necessitate usage of \input, because it is either \commands or filename. However that possibility looks very obsolete because it is long since that "latex" command is aliased to pdfetex in a way which sets \pdfoutput without having to do it manually. B. About this in the patch under discussion + ;; Since TeXLive 2018, the default encoding for LaTeX files has been + ;; changed to UTF-8 if used with classic TeX or pdfTeX. I.e., + ;; \usepackage[utf8]{inputenc} is enabled by default in (pdf)latex. + ;; c.f. LaTeX News issue 28 + ;; Due to this change, \detokenize is required to recognize non + ;; ascii characters in the file name. The exact explanation would be that this is required in case the \input method of executing the file is used. It is not required in the case of "pdflatex filename" invocation, not because the non-ascii letters are not handled in a special way but because they are handled in a self-innocenting way as long as \everyjob has not been executed after which they acquire their proper \usepackage[utf8]{inputenc} form.
