TextMesh Pro TMP_InputField causes ArgumentOutOfRangeException in TouchScreenKeyboard

Unity 2019.4.20f1, TextMeshPro2.1.6

I have a few users that run, according to Cloud Diagnostics, in the following issue:

Code (CSharp):

1. UnityEngine.TouchScreenKeyboard.set_selection (UnityEngine.RangeInt value)
2. TMPro.TMP_InputField.ActivateInputFieldInternal ()
3. TMPro.TMP_InputField.LateUpdate ()

The following warning is logged as well, might be related:

Code (CSharp):

1. The character with Unicode value \uFFFC was not found in the [merriweather_black_latin] font asset or any potential fallbacks. It was replaced by Unicode character \u0020 in text object [text].

I don't know how to reproduce the issue. Perhaps you (Stephan) know and it helps you to fix the problem.

This should have been fixed in 2.2.0-preview.2.

 

Thank you for the reply.

Do you happen to know how I could reproduce this issue? I would love to be able to reproduce it, so I can also test it myself whether the update fixes it.

 

Many of these appear to be timing related on some devices. As such, it has been hard to reproduce many of these which was happening more frequently when selecting multiple characters and using insert or delete. I added a range check on those arrays which will ensure the indexes are correct but reproducing was still challenging.

Preview 3 will also include additional changes / tweaks related to this.

 

In the meantime we updated to Unity 2021.3.11f1 and TextMeshPro 3.0.6, but unfortunately, we still see this issue. Exact same error message as posted in the first message (link).

I can't find a newer TMP version in the Package Manager window, so I suppose the issue is fixed in a newer version than 3.0.6 that's no longer compatible with Unity 2021.3?
