DESCRIPTION

56       All of the routines described examine Tcl_UniChars and return a boolean
57       value. A non-zero return value means that the character does belong  to
58       the  character  class  associated  with the called routine. The rest of
59       this document just describes the character classes associated with  the
60       various routines.
61
62       Note:  A Tcl_UniChar is a Unicode character represented as an unsigned,
63       fixed-size quantity.

CHARACTER CLASSES

67       Tcl_UniCharIsAlnum tests if the character is  an  alphanumeric  Unicode
68       character.
69
70       Tcl_UniCharIsAlpha  tests  if  the  character  is an alphabetic Unicode
71       character.
72
73       Tcl_UniCharIsControl tests if the character is a Unicode control  char‐
74       acter.
75
76       Tcl_UniCharIsDigit  tests if the character is a numeric Unicode charac‐
77       ter.
78
79       Tcl_UniCharIsGraph tests if the character is any Unicode print  charac‐
80       ter except space.
81
82       Tcl_UniCharIsLower  tests if the character is a lowercase Unicode char‐
83       acter.
84
85       Tcl_UniCharIsPrint tests if the character is a Unicode print character.
86
87       Tcl_UniCharIsPunct tests if the  character  is  a  Unicode  punctuation
88       character.
89
90       Tcl_UniCharIsSpace tests if the character is a whitespace Unicode char‐
91       acter.
92
93       Tcl_UniCharIsUpper tests if the character is an uppercase Unicode char‐
94       acter.
95
96       Tcl_UniCharIsWordChar  tests if the character is alphanumeric or a con‐
97       nector punctuation mark.
