Sublang

From ReactOS

General Rules

• If the primary language has only one sublanguage, use SUBLANG_DEFAULT or SUBLANG_NEUTRAL.
  We highly recommend using SUBLANG_DEFAULT here, but to retain compatibility with the Wine Sublang Rules we also allow using SUBLANG_NEUTRAL. This means that you also shouldn't change SUBLANG_NEUTRAL to SUBLANG_DEFAULT in a component we share with Wine.
• If the primary language has more than one sublanguage and we have no general translation for this primary language yet, use SUBLANG_NEUTRAL for the general translation.
• If the primary language has more than one sublanguage, we already have a general translation for this primary language and you want to add a translation specifically for this sublanguage, use SUBLANG_SubLanguageName for this specific translation.

Exceptions of these Rules

• If the primary language is LANG_ENGLISH and you want to add a general english translation, you have to use SUBLANG_ENGLISH_US.
  Every file, which contains translations, should have a LANG_ENGLISH, SUBLANG_ENGLISH_US translation as this is also used as a fallback.
• For LANG_IRISH, you cannot use SUBLANG_DEFAULT. In this case, you have to use SUBLANG_IRISH_IRELAND.
• If you want to add a chinese translation, decide on either SUBLANG_CHINESE_SIMPLIFIED or SUBLANG_CHINESE_TRADITIONAL.
  As both languages differ very much in the used alphabet, we should set no default or neutral language here.
