Abstract:

Unicode has the concepts of code unit (1 byte in UTF-8) and code point (1--4 bytes in UTF-8). It does not clearly define "character"; a glyph can consist of several code points. UTF-8 works great with Forth-94: Use strings to represent glyphs (or sequences of glyphs). Therefore the xchar words see little use, but they are there if you really want to deal with code points.
