[m-users.] Unicode character ordering

[Volker Wysk]

Hi

The unicode support of mercury looks like it's incomplete... In
particular, I'm looking for a unicode character ordering function. The
standard ordering does a bad job with unicode characters.

For Haskell, there is the RFC5051 library, which defines a unicode char
ordering. It works pretty well.

Perhaps I could port it from Haskell to Mercury...

Cheers,
Volker
