In the Unicode world a non-ASCII-character is not an 8 bit entity. So,
with the current compiler version, (unexpectedly) a single quoted
non-ASCII character is an UTF-8 coded string, while a single quoted
ASCII character is a character. (I feel this might change with a future
compiler version when D2010 strings might be introduced).

Unless you want to use the old style (depreciated) locale-dependent 8
bit ANSI encoding you could enumerate characters as 16 (or even 32 Bit)
Unicode numbers. AFAIK appropriate conversion functions are available in
the RTL.
