I mean character categories defined in 

http://www.unicode.org/Public/4.1.0/ucd/UCD.html#General_Category_Values

Abbr.  Description
 
Lu Letter, Uppercase 
Ll Letter, Lowercase 
Lt Letter, Titlecase 
Lm Letter, Modifier 
Lo Letter, Other 
Mn Mark, Nonspacing 
Mc Mark, Spacing Combining 
Me Mark, Enclosing 
Nd Number, Decimal Digit 

etc., total about 30 or so. isxxxrune distinguishes only among 5 categories.

This would probably inlcude diacritics, but my question was more
general (maybe even philosophical): there exists a recommended set of
Unicode character properties, APIs, and interfaces (Unicode.org).
Plan9 which probably influenced some aspects of Unicode to be
implemented in other systems does not follow. Is there any historical
/political /technical /other reason? Related man pages mention "The
Unicode Standard" though in SEE ALSO section.

What is more interesting to me (technically, as I asked in my first
message) - is 16-bitness of runes hardcoded anywhere in the kernel, or
only in libc?
