30 78e51a8c 2005-01-14 devnull .SH DESCRIPTION
31 78e51a8c 2005-01-14 devnull These routines examine and operate on Unicode characters,
32 78e51a8c 2005-01-14 devnull in particular a subset of their properties as defined in the Unicode standard.
33 78e51a8c 2005-01-14 devnull Unicode defines some characters as alphabetic and specifies three cases:
34 78e51a8c 2005-01-14 devnull upper, lower, and title.
35 78e51a8c 2005-01-14 devnull Analogously to
36 78e51a8c 2005-01-14 devnull .IR isalpha (3)
37 78e51a8c 2005-01-14 devnull for
38 78e51a8c 2005-01-14 devnull .SM ASCII\c
39 78e51a8c 2005-01-14 devnull ,
40 78e51a8c 2005-01-14 devnull these routines
41 78e51a8c 2005-01-14 devnull test types and modify cases for Unicode characters.
42 78e51a8c 2005-01-14 devnull The names are self-explanatory.
43 78e51a8c 2005-01-14 devnull .PP
44 78e51a8c 2005-01-14 devnull The case-conversion routines return the character unchanged if it has no case.
