RE: lag time in Unicode implementations in OS, etc?

Windows 2000 does support surrogates as defined in Unicode 2.0 e.g. it
recognizes them when
converting to/from UTF-8 & OpenType recognizes new cmap types for
surrogates.

The remaining steps e.g. fonts that display Ext B and sorting methods
that integrate surrogate
pairs in culturally correct ways, depend on the final assignments of the
new ranges. That isn't
in Unicode 2.0 (or 3.0).

which standard? unicode 2.0 introduced surrogates in 1996. iso 10646-1
got amended with utf-16 in 1996, too.
there was nothing new in the technical issues of how to deal with utf-16
since then.
