public String toUpperCase (Locale locale)

Converts all of the characters in this String to upper case using the rules of the given Locale. Case mapping is based on the Unicode Standard version specified by the Character class. Since case mappings are not always 1:1 char mappings, the resulting String may be a different length than the original String.

Examples of locale-sensitive and 1:M case mappings are in the following table.

Language Code of Locale Lower Case Upper Case Description
tr (Turkish) \u0069 \u0130 small letter i -> capital letter I with dot above
tr (Turkish) \u0131 \u0049 small letter dotless i -> capital letter I
