32 b2cfc4e2 2003-09-30 devnull .SH DESCRIPTION
33 b2cfc4e2 2003-09-30 devnull These routines examine and operate on Unicode characters,
34 b2cfc4e2 2003-09-30 devnull in particular a subset of their properties as defined in the Unicode standard.
35 b2cfc4e2 2003-09-30 devnull Unicode defines some characters as alphabetic and specifies three cases:
36 b2cfc4e2 2003-09-30 devnull upper, lower, and title.
37 b2cfc4e2 2003-09-30 devnull Analogously to

41 b2cfc4e2 2003-09-30 devnull ,
42 b2cfc4e2 2003-09-30 devnull these routines
43 b2cfc4e2 2003-09-30 devnull test types and modify cases for Unicode characters.
44 b2cfc4e2 2003-09-30 devnull The names are self-explanatory.

46 b2cfc4e2 2003-09-30 devnull The case-conversion routines return the character unchanged if it has no case.
