.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.
