However, there could be lots of encodings that are not ASCII compatible (but in practice, probably very few, since most encodings _are_ ASCII compatible) that could be fit those constraints. So while as a technical matter, Cameron is correct that Unix only treats 0 & 47 as special, and that is insufficient to declare that encodings must be ASCII compatible, as a practical matter, since most encodings are ASCII compatible anyway, it would be hard to find very many that could be used successfully with Unix file names that are not ASCII compatible, that could comply with the 0 & 47 requirements. -------------- next part -------------- An HTML attachment was scrubbed...
