Character operations

The IBM® Informix® GLS library supports character classification, case conversion, and code-set conversion operations on multibyte and wide characters.

Character classification
A GLS locale groups the characters of a code set into character classes. Each class contains characters that have a related purpose.
Case conversion
In many languages, alphabetic characters have an uppercase and lowercase representation. Your application must not assume the case equivalent for a particular character.
Code-set conversion
A character might be encoded differently on two different operating systems. Therefore, the appropriate communication layer must be prepared to convert between the two encodings.
