22.8 Unicode character and string functions

This section lists functions which compare characters and strings similarly to cl:char-equal , cl:string-greaterp and so on, but which use Unicode's simple case folding rules.

There are also predicates for properties of characters in Unicode's "general category", corresponding to cl:alpha-char-p , cl:both-case-p and so on.

22.8.1 Unicode case insensitive character comparison

22.8.2 Unicode case insensitive string comparison

22.8.3 Unicode character predicates
