You probably already know that ISO/IEC JTC1/SC22/WG20 is working on a
default tailorable ordering standard (ISO/IEC 14651) for the UCS which
defines the ordering in terms of LOCALES with slight extensions to POSIX
syntax, don't you?

Keld Simonsen is also working on the complement of this standard (ISO/IEC
14652) which will define the syntax and the rest of the default "universal
LOCALE" for such things as upper/lower.
