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 <a href="../man3/isalpha.html"><i>isalpha</i>(3)</a> for
|
||
|
|
ASCII, these routines test types and modify cases for
|
||
|
|
Unicode characters. The names are self-explanatory.

The case-conversion routines return the character unchanged if
|
||
|
|
it has no case.<br>
