28000 is the number of ideographic far eastern characters in Unicode V3,
*NOT* the full number of characters used. Unicode V3. specify 49194 characters,
6400 private use characters, 2048 surrogates, and misc other values, ending up
at 57709 assigned 16-bit values...
This is up about 10.000 from V2.1, and this rate of adding characters aren't
likely to stop anytime soon (there's still lots of scripts to add, and lot of
discussion about adding more versions of some glyphs - many people want separate
Chinese and Japanese versions of symbols that are currently represented by one
glyph in Unicode, for instance).
In other words: 32 bit *will* be used in the next versions of Unicode (post 3.0)
However this won't be a problem as long as one of the UTF-* encodings are used,
and not UCS-2.
