Thanks a a lot. That's useful info.
Your suggestions do fix the problem.

Character ranges are locale-dependant. Check the
values of LC_ALL and LC_COLLATE. Under some locales, the [A-Z]

character classes, i.e. [[:alpha:]], [[:lower:]], [[:upper:]],
Unless you set the globasciiranges shopt:
If set, range expressions used in pattern matching bracket
expressions (see Pattern Matching) behave as if in the
traditional C locale when performing comparisons. That is, the
current locale’s collating sequence is not taken into account,
so ‘b’ will not collate between ‘A’ and ‘B’, and upper-case and
lower-case ASCII characters will collate together.
Anyways, bash behavior here is correct. If you need
some specific collation order make sure to set your LC_*
variables correctly, or use the POSIX locale (LC_ALL=C)
