To Reproduce

Try to match an element with an emoji in it. I tried both with the emoji utf-8 character pasted in and it's escaped \u00a0\uD83D\uDD01 representation.

Expected behavior

To be able to match emojis etc.

Screenshots

Environment (please complete the following information):

• Detox: 13.0.2
• React Native: 0.59.9

Interesting usecase. I will try to reproduce and see where it fails, but we might be limited with what we can do to counter this. If it's an issue with how we encode strings, this can be solved. If it's an issue with Earl Grey, we most likely won't be able to.

We are working on replacing the current matching infrastructure. This will hopefully be resolved once we move to the new system.

This should be solved in a future release. We now use standard NSPredicate to match views, so emoji (or any unicode string for that matter) should be natively supported.
