Cannot use Emojis to begin names of Check Run workflows

Body

Workflow names can start with Emojis. It's cute.

However, if they are being used for check runs, the https://github.com/<org>/<repo>/branches/authorization_suggestions?name=main&type=dismiss&q= endpoint throws an "oops" when searching for an Emoji.

This means that such workflows cannot be used to gate pull requests.
