Locales can have special variants, to indicate the use of particular calendars, or other features. They be used to select among different options in menus, and also display which options are in effect for the user.
Here are the names of Options to be translated.
| Option | Meaning |
|---|---|
| Calendar | Calendar system (the European calendar is called “Gregorian”; others are the Chinese Lunar Calendar, and so on.) |
| Collation | How text is sorted (where a language has different possible ways to sort). |
| Currency | The default currency. (The value is any currency value, such as USD). |
| Numbers | The numbering system in use, such as European (0,1,2), Arabic (٠, ١, ٢ ), Devanagari ( ०, १, २ ). - Usually these are just derived from the name of the script. - There are some special forms, such as " Simplified Chinese Financial Numerals " or " Full Width Digits ". |
| Private Use | Used for Private-Use options (x). |
The following are some examples of Option+Value combinations that need translation. Where the Value for the Option is not from a small set (Currency and Private Use), then the Locale Option Pattern is used (see Language/Locale Name Patterns.
