AFAIU, uppercasing is locale-insensitive operation. Case (none, uppercase,
lowercase or titlecase) is the property of character and may be changed
appropriately. Files UnicodeData.txt, SpecialCasing.txt and
CaseFolding.txt from Unicode standard clearly specify case conversion
rules. This means that default case conversion may be safely added
to all Firebird character sets as they are all have direct UNICODE
mappings.
