Yes, indeed. And the quoted passage in the GNU manual says about ord()...
"the numeric value for that character in the machine's character set".

While this matches the interpretation I am comfortable with - in this
case and also with the ranges of characters in regexps, the quoted
link about "Character-Lists" explicitly mentions a locale dependency.

man regex(7) also doesn't enlighten the topic; in one sentence they
talk about a _character set_ ("`[0-9]' in ASCII matches any decimal
digit"), and shortly after that they talk about _collating sequences_
("Ranges are very collating-sequence-dependent").

I'm still puzzled about that.
