.SH DESCRIPTION
|
|
.PP
|
|
All of the routines described examine Unicode characters and return a
|
|
boolean value. A non-zero return value means that the character does
|
|
belong to the character class associated with the called routine. The
|
|
rest of this document just describes the character classes associated
|
|
with the various routines.
