Due to the
MODx#138, I have renamed the French folder in francais-utf8 to be conform to the most used character set in French for the manager. But now francais-utf8 is proposed as language for the installer >:( (and japanese-utf8 for japanese pepole).
IMHO, we mix the language and the character set. A french guy which want a site with a charset=iso-8859-1 could think that this choice done during the installation is definitive!. He don’t know that he could change later.
So, I haven’t checked that is it possible, but I suggest to keep the folder and file as "francais-utf8" or "japanese-utf8", but also filter the language label and displayed only "francais" or "japanese"
Thanks for your feedbacks about this remark.
