Yes, mine too. I just extrapolated a sample section.

However, that file is included by many other files in that directory
(notably, not by POSIX).

$ grep -l 'copy "i18n"' /usr/share/i18n/locales/* | wc -l
99

Does that mean that all these 99 locales have all the same characters in
their upper, alpha, etc. classes?

And, even if it is so, that helps only for POSIX character classes; how
does
one answer the question "what characters match, eg, '[A-Z]' under a given
locale?". I think the answer to this lies in the understanding of
LC_COLLATE.

I guess I'll try reading the standard doumentation for localization when I
have more time. It scares me a little bit because its language is not (to
me at least) much simple and clear (unlike other parts of the standard),
however I think it's an obligatory step to understand the whole thing
better.

Thanks for your persisting interest in this discussion!
