That said, bash is within its rights to add, as an extension to the
standard, the use of any valid letter within the current locale.  But
someone would have to write a patch to do that, and make sure that such
a patch doesn't adversely affect speed, and that such identifiers don't
break when you switch to another locale where the same byte pattern is
no longer composed of valid letters.
