Again, I think it's OK if i18n support only works with glibc and
similarly capable C libraries – provided this is well documented and
probably shown in the output of `--version`.
Right now, there is *no* i18n support in `texindex`. With some small
changes, there would be *full* support for a particular but important
set of OSes. Not too bad IMHO.
It's up to the maintainers of texinfo to decide where to draw the
support line, but honestly, I can't imagine that they want to enter
the muddy waters of collation support for all platforms.
