ISO 15897 format of country specific locales

[bjoerne2]

On https://laravel.com/docs/7.x/localization it says:

For languages that differ by territory, you should name the language directories according to the ISO 15897. For example, "en_GB" should be used for British English rather than "en-gb".

Wouldn't it be better to rename the country specific folders, e.g. de-CH -> de_CH?

Good idea, we need to do a new major version ( v7 ), because we brake directory names...

Can you do a pull request ?

I created a PR: #1276

[caouecs]

Can I have references for language names ? As sr_Cyrl

[caouecs]

My problem is for sr_Cyrl, sr_Latn, uz_Cyrl and uz_Latn.

Either I read the technical documentation poorly, or in the description of the ISO 15897:1998 standard there is no mention of the rules for naming language localizations.
Standard ISO 15897:2011 is paid ($168...) 😐

I may be wrong, but I want to propose to call it this way:

de_CH
pt_BR
...
sr_Cyrillic
sr_Latin
uz_Cyrillic
uz_Latin

done

Thank you
