Crash when using scrcpy and typing umlauts (ä, ö, ü) on the PC keyboard

[matterharz]

Does it happen in OpenBoard, or is it exclusive to this modified version?
It's exclusive to this modified version. Doesn't happen with the F-Droid release and with none of my other installed keyboards: stock, Florisboard, Florisboard Beta, Thumb-Key

Describe the bug
I'm connected to my smartphone from my Windows 10 PC via scrcpy. When I type any umlaut (ä, ö, ü) on the PC keyboard, the app crashes. The typed characters look like this (it crashed 3 times when typing those):

To Reproduce

1. Connect phone via scrcpy, doesn't matter whether it's over USB or tcpip. Also no additional options like --prefer-text or anything (cf. Umlauts don't work Genymobile/scrcpy#431)
2. Type umlaut. ("ß" -- to mention that uniquely German letter -- works fine)
3. Crash (from Scoop):

The crash should be fixed, not sure though whether the letters will appear correctly.

[matterharz]

Well, that was quick. Will report back with the next release. Thanks!

[Helium314]

Did you try with the latest release 1.0-alpha1?

[matterharz]

Oh, thanks for reminding me. It's working fine, the characters also appear correctly!
