Traditional Chinese characters are not supported on iOS.
Hybrid Apps that have names that begin with numbers or special characters cannot be localized; you will receive an error when you generate the code. Make sure that any Hybrid App you want to localize does not have a file name that begins with a number or special character.
When you specify a country for the language, the basic language locale must also be available. For example, if you create a locale and specify English as the language and the United States as the country, then a locale for English (the basic language) must also be available.
If you create a locale that specifies language, country, and variant, the locale for the basic language and the locale for the basic language and the country must be available. For example, if you create a locale and specify English as the language, United States as the country, and WIN as the variant, then English (United States) and English locales must also be available.
The language code must be a 2-letter code, and the country code
can be either a 2-letter or 3-letter code.

Asia simulators do not have a place to specify a country name, so you can
