| .SH DESCRIPTION
| These routines examine and operate on Unicode characters,
| in particular a subset of their properties as defined in the Unicode standard.
| Unicode defines some characters as alphabetic and specifies three cases:
| upper, lower, and title.
| Analogously to
| .IR isalpha (3)
| for
| .SM ASCII\c
| ,
| these routines
| test types and modify cases for Unicode characters.
| The names are self-explanatory.
| .PP
| The case-conversion routines return the character unchanged if it has no case.
