public class CaseFolding
- extends Object
Utility for case folding Java Strings. This follows the advice given here. Basically the value is case folded by calling
String.toUpperCase(locale).toLowerCase(locale)
. This is a little better than calling only String.toLowerCase(locale)
. For example, in German the string "ß" upercase equilavent is "SS". If we only
called only String.toLowerCase(java.util.Locale)
we would store "ß"in the index which would make
matching "SS" impossible. This does not always case fold correctly, for example the Turkish 'I', but it is a good
compromise.
