IBM Informix products can support many languages, cultures, and code sets. All culture-specific information 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. These locales support U.S. English format conventions for dates, times, and currency, and also support 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 non-ASCII characters in your data or in SQL identifiers, or if you want to conform to localized collation rules of character data, you need to specify an 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.
