If you will list allowed characters (instead forbidden) you don't need
way how to enter C0 and C1 characters as those can't be expressed in XML
anyway.

If we need to restrict characters that are allowed for translations
regexes are minimum. For some languages even more complex solutions
which work on top of regexps might be needed, for example CREPDL schema
language:

We really shoudln't reinvent wheel and use existing standardized stuff.
Having comma separated list of forbidden characters is something which
is not used elsewhere.
