Comments.Text: @BradBell What I need is a combination of the Dutch number notation (decimals / thousands) and the rest of the site can use the English rules. So my idea was putting a duplicate `en.php` file in the `config/locales/` folder with those specific changes to override the default one.

  (Asked by: username_0 on 2018-07-19)
  
  I am looking for a way to add new locale files or override existing ones.
  
  Basically a Craft 3 version of this: <https://craftcms.com/support/adding-additional-locales>
  
  I've tried the way described here: <https://github.com/craftcms/locales>
  
  But that does not seem to be picked up by Craft 3.

  Haven't actually tested this, but looking at the code I think it should work.
  
  You'll need to disable the intl extension from being loaded on your box (usually done in php.ini) because if Craft sees that's available, it will use that automatically.
  
  If it's not available, it falls back to `config/locales`, which is where you should be able to put your "custom" locale.
