Can we access your project?

• [ ] I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

When I paste a regex pattern into the text input validation field, any instance of :( within the pattern is automatically converted into an emoji.

Attached is a screenshot of the issue:

Expected Behavior

The regex pattern should be pasted exactly as written.

Steps to Reproduce

1. In any FlutterFlow project, add a TextField inside a Form.
2. Select 'Custom Regex' in the 'Text Validator' field.
3. Paste the following regex: ^([01]\d|2[0-3]):([0-5]\d)$

Reproducible from Blank

• [ ] The steps to reproduce above start from a blank project.

Hello!

Thank you for bringing this to our attention!

I can confirm the issue you’ve encountered, but rest assured, it is only a visual bug when using certain fonts in the FlutterFlow Builder. The underlying code correctly displays the Regex as it should, so you can safely continue using it without any concerns.

Thank you again for reaching out!
