Allow addtional "tokens" in the locale, additional to language and country

Problem

As I was trying to organize some translations, I found myself in the situation that I need to use not only language and country to define the locale, but also a variant.

For example (not the real situation but hopefully to illustrate)

• de = German
• de-DE = German / Germany
• de-DE-bavarian = German / Germany / Bavarian

Using your Beta v2.0 WiP I found, that 3rd locale de-DE-bavarian will not be shown neither in the Progress view nor in the editors popup, where the translations are shown. Only de and de-DE will be visible.

Reference to Java locale

For example in the Java documentation 7 and 8 there are mentioned two “non-conforming locales” ja_JP_JP and th_TH_TH.

Additionally the documentation suggests extensions to the locale, see there.

Another link is this in Table 5. Some of the Supported Locales in java.util and java.text Packages

| Language | Country | Locale ID | | … | … | … | | Thai (Western digits) | Thailand | th_TH | | Thai (Thai digits) | Thailand | th_TH_TH |

Suggested solution

Thus I would suggest, that the locale can be created from a - theoretical endless 😉 - number of tokens, with the only constraint, that

• the first token defines the language
• the second token defines the country and is used to retrieve the country flag

For a more official use of locale, you can see above

• th_TH= Thai (Western digits) Thailand
• th_TH_TH = Thai (Thai digits) Thailand

BTW, can you provide me more information about how you use Java and i18n in VS Code? It’s good for me as a reference to support wider use cases.

Sorry for not being clear enough:

• At my previous job - years ago, implementing Java with Eclipse - we used the variant part of locale() to localize some vendors text (like item number, #, item#, etc.).
• Right now I’m playing around on some hobby project - implementing in JS and PHP, and that feature came back into my mind.
