Re: [csswg-drafts] [css-text] text-spacing is very complicated (#4246)

The JIS standard defines a set of character classes and their relationships in terms of a spacing range and compression/expansion priority, but there are problems with how these classes are defined (not differentiating between proportional/half-width/full-width for example) as well as no consideration of mixed script text. We need a modular approach that defines the character classes, the spacing ranges (with priority) of each class pairing, according to the needs of the UA and how fancy it wants to be when supporting complex layout. A reasonable default behavior could also be proposed as part of the jlreq, I would hope, so the spec could then be about a sparse override of the default.
