The locales file has platform-specific sections. An entry defines a locale as the combination of a language, character set, and sort order:
locale = locale_name, language_name, charset_name [,sort_order_name]
If the sort order is not specified, it is “binary.”
When the locale being defined is the default for the site, the locale_name is “default.” For example, this entry defines the default locale as us_english with the iso_1 character set and binary sort order:
locale = default, us_english, iso_1
