 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 isalpha(3) 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.
