For now, I'm adding a `char-general-category' procedure that returns a
symbol: 'lu, 'll, 'co, etc.

 * We can revisit the question of symbols versus enumerations if we add
   enumerations to R6RS.

 * I don't like long names, such as "private use" instead of "Co",
   because I'll never remember the long version, and there seems to be
   no standard other than the two-letter name. And I used case-folded
   symbols, such as 'co instead of 'Co. Other suggestions are welcome.
