Description

The functions unicode-char-not-greaterp and unicode-char-not-lessp return true if the character char1 is not greater (or for unicode-char-not-lessp, not less) than the character char2, similarly to cl:char-not-greaterp and cl:char-not-lessp but ignoring case using Unicode rules specified by style.

The current implementation only supports one style of comparison:

Compares characters using the simple lowercase folding rules in Unicode 6.3.0.
