I was thinking about localising TeX a while ago too, but I was thinking
in a more conventional way: using GNU gettext to localise TeX messages,
then the localisable strings can be extracted using gettext tools into a
regular PO file that people can translate, convert to MO files and
install alongside LuaTeX. But there might some issue that need to be
considered first e.g. should messages written into log be localised too?
Should there be an explicit switch to select locales or just use the
system locale etc.
