Variable length multi-byte is fine -- think UTF-8. The important thing is 
actually that the codec be ASCII-compatible. Preferably, it should be a 
superset of ASCII (like the ISO-8859 family, the Windows 1250-1260 codepages, 
most old DOS codepages), but in practice codecs like SJIS are also acceptable. 
Wide character codecs aren't, ASCII-incompatible codecs neither.

Try explaining to a Japanese user that the path separator on Windows isn't ¥.
