It's not that the Ada mode is assuming any specific version. There's a
variable `ada-language-version', but it just affects which keywords
are recognized as such. The problem is simply that some of the regexps
were written in the ASCII-only era and have not been updated.

Try the following patch, which should fix this particular case. I'll
bring the issue to the Ada mode maintainer for a more permanent fix.
