IBM Informix products can support many languages, cultures, and code sets. All the information related to character set, collation, and representation of numeric data, currency, date, and time is brought together in a single environment, called a Global Language Support (GLS) locale.
This manual assumes that you use the U.S. 8859-1 English locale as the default locale. The default is en_us.8859-1 (ISO 8859-1) on UNIX platforms or en_us.1252 (Microsoft 1252) for Windows environments. This locale supports U.S. English format conventions for date, time, and currency, and also supports the ISO 8859-1 or Microsoft 1252 code set, which includes the ASCII code set plus many 8-bit characters such as é, è, and ñ.
If you plan to use nondefault characters in your data or your SQL identifiers, or if you want to conform to the nondefault collation rules of character data, you need to specify the appropriate nondefault locale.
For instructions on how to specify a nondefault locale, additional syntax, and other considerations related to GLS locales, see the IBM Informix: GLS User's Guide.
