The functions
unicode-char-greaterp
and
unicode-char-lessp
return true if the character
char1
is greater than (or for
unicode-char-lessp
, less than) the character
char2
, similarly to
cl:char-greaterp
and
cl:char-lessp
but ignoring case using Unicode rules specified by
style
.
The current implementation only supports one style of comparison:
Compares characters using Unicode's simple lowercase folding rules.
