Changing labels for existing production capability

Only the internal team has permission to change the translation of a custom capability, they help us change it in case there’s an error.
When you set a custom label in the device presentation, the change of language doesn’t affect it. If you want to use Simplified Chinese as the default language, I think you can set the custom label using it, I haven’t tried using those kinds of symbols but as the label is a text, it should accept them.
