Description

Example: The 'İ' (U+0130) is composed by two bytes. But its lowercase is composed by 1 byte. It was throwing errors, but correct result would be:

SQL> SELECT LOWER('İA') FROM RDB$DATABASE;

LOWER
========
ia

SQL> SELECT LOWER('AӴЁΪΣƓİ') FROM RDB$DATABASE;

LOWER
============================
