| |
| 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. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| The case-conversion routines return the character unchanged if |
| it has no case.<br> |
