Types of characters

A GLS locale supports a particular code set, which maps characters to unique bit patterns called code points.

A particular code set can contain the single-byte characters or multibyte characters.

For a general introduction to code sets, single-byte characters, and multibyte characters, see the HCL Informix GLS User's Guide.

Use of the HCL Informix® GLS library helps to remove most assumptions about the type of character that your application handles.
