When not in Posix mode, bash doesn't really have any restrictions on
characters that can be used in function names.  It's basically the same
namespace as external commands, with a few exceptions (no dollar signs,
no quoted strings, no all-digit names). You can even name a function
`/bin/true' and call it, as long as you quote the slashes.  With so few
restrictions, there's nothing to supporting locale-specific function
names -- they're just a string of bytes.
