Hi,
I'm using Windows. Luatex interprets the command line as if it were
UTF-8, so I cannot write accents in the file names. E.g.:
luaplainJA Canción.tex
This is LuaTeX, Version beta-0.76.0-2013052306 (rev 4627)
! String contains an invalid utf-8 sequence.
<*> Canci
¾n.tex
?
Can just Luatex ask some C library IO function to open the name it was
passed in, without it trying to be too smart parsing the name?
If this is not posible, those of you who use Windows, how do you solve it?
Not being able to write accents or other kinds of characters in the
filename is a déja-vu form the protohistory of informatics. If Luatex
cannot just open the file, it should at least process the commad line
transforming it from the platform-locale specific encoding to UTF-8,
thence passing the arguments & filename to whatever routines it wants.
this is a tricky issue as jobnames can end up anywhere in (lua)tex so
also in places where it definitely has to be utf
also, there is nothing that forbids filenames to have any characters so
there is no robust way to identify in what encoding (codepage) the
filename is, especially as files can come from anywhere (a unix based
nas running samba, external resources like graphic studios using osx or
whatever, some script that makes up a name)
(you can of course create files with utf 8 filenames on windows)
ps. this is not unique to windows and/or luatex ... i've run into issues
with media servers running on linux machines that also had issues, not
barking like tex, but for instance entering loops which to some extend
is worse
(one option is to write a wrapper script that translates from your
current codepage to utf, hoping of course that you don't get files from
someplace else with another encoding; internally windows uses utf16 but
i'm not sure if that helps much)
