---------------------------------------
Hi [~rolandkreuzer]
Your approach sounds reasonable. I think we'll need to see it in a PR to
understand any possible side-effects, tests, and so on.
TY!

> The {{toLocale()}} method is unable to handle locale strings that have custom
> extensions that are completely valid according to the [BCP47
> spec|https://tools.ietf.org/html/bcp47#section-4]. Oracle documentation for
> sub tag extensions can be [found
> here|https://docs.oracle.com/javase/tutorial/i18n/locale/extensions.html].
> An example locale string with a custom extension might be {{fr-CA-x-nb}}.
> This issue seems to have been introduced with ticket LANG-915.
