User-defined locales

Informix® JDBC Driver uses the Java™ globalization API to manipulate international data.

The classes and methods in that API take a Java™ development kit locale or encoding as a parameter, but because the Informix® DB_LOCALE and CLIENT_LOCALE properties specify the locale and code set based on Informix® names, these Informix® names are mapped to the Java™ development kit names. These mappings are kept in internal tables, which are updated periodically.

For example, the Informix® and Java™ development kit names for the ASCII code set are 8859-1 and 8859_1, respectively. Informix® JDBC Driver maps 8859-1 to 8859_1 in its internal tables and uses the appropriate name in the Java™ development kit classes and methods.
