Hello Bruno,

You can work around it by using the System V way of writing ranges:
tr '[a-z]' '[A-Z]'
which will work with both types of tr programs for this range.

Posix already documents this in more detail than we do. I don't think
we should repeat each oddity that Posix already documents (but in this
particular case, I don't care much either way, as long as we mention
the workaround above).

Fine with me.
Thanks,
