unicode-string-equal

Description

The functions unicode-string-equal and unicode-string-not-equal compare the designated substrings of string1 and string2, ignoring case using Unicode rules specified by style. The values of start1 and start2 default to 0, while the values of end1 and end2 default to nil.

The returned value flag of unicode-string-equal is true if the strings are equal and false otherwise.

The returned value mismatch-index of unicode-string-not-equal is the index where the strings mismatch (as an offset from the beginning of string1) or nil otherwise.

The current implementation only supports one style of comparison:

:simple-case-fold

Compares each character of the strings using the simple case folding rules in Unicode 6.3.0.
