From http://unicode.org/reports/tr21/tr21-5.html#Caseless_Matching: Case-folding is the process of mapping strings to a canonical form where case differences are erased. Case-folding allows for fast caseless matches in lookups, since only binary comparison is required. Case-folding is more than just conversion to lowercase.
Case folding is not culture aware. String comparisons that should be culture aware should not use this method.
