Description

Typing a single emoji character into the text view, then tapping the right button (Send in the sample app), causes the text view font to change from system to a courier style font. This has been verified in the iOS Slack app as well.

Reproducible in:

• [x] This is reproducible in the sample project. SlackTextViewController version: 1.9.5 iOS version(s): 10.0 Device(s): All

Steps to reproduce:

1. Enter a single emoji in the sample app text view (only certain symbols will trigger the issue, ❤️, ☢️, ♒️ are examples that will cause it).
2. Tap 'Send'
3. Start typing in the text view. The font has changed to a courier style font. Tapping back with an empty text view and then returning to the messages view will cause the font to revert.

We've been seeing this too since iOS 10 came out, but didn't happen on the betas. Thanks for such a descriptive issue report. We will try to fix it but it almost feels like a UITextView issue so far.

Was this fixed? I have a similar problem in my project.

@dzenbot @enstulen @je7db Same thing happens with UI Label text ... No ideas so far?
