Typing in console from mobile device is causing double characters about daedalos HOT 11 CLOSED

Almost completely worthless after I compressed it to fit on GH, but this is a video recreating the issue. No real idea what to suggest. I believe I initially found this on A10, and have upgraded my device to A11 where it still reproduces.

Thanks for the clear bug report. This should be enough for me to look into it, thanks!

It doesn't happen on my S21 or S8 but I have indeed noticed it in BrowserStack. I will try and understand what is happening with the Keyboard events. Any suggestions welcome.

Okay, some more information.

The only two keyboards I tested which worked without issue were Hacker's Keyboard and Gboard, but only in handwriting mode.

Gboard in regular mode, SwiftKey, and Unexpected Keyboard showed the double characters. Swype wasn't showing double characters, but would seemingly auto-correct when pressing return.

So in a way not completely useful, the behavior is influenced by the keyboard and the behavior isn't consistent in a way I'd expect.

I'm going to guess that you are using Samsung's default keyboard for the devices you've tested which work?

Thinking about the pattern here, the keyboards which I know that fail, they are looking at the edit textbox buffers to provide corrections. The way we did this with Swype years ago, was that we'd actually send keys to the buffer to delete text and replace it. I'll bet that Hacker's Keyboard doesn't try to hook into the buffer at all. That would be a path to investigate. What the keyboards are reading from the buffer is probably incorrect in some way, maybe UTF-8 vs. ASCII characters? If there's some encoding problems the character streams might be getting confused.

Thanks for this detailed report! I will spend some time looking at this during the week. I think I just need to do some better debugging as to what keyCode's I am getting because tbh I haven't dug deep enough yet.

I have found this is a common issue on other websites with a console type interface e.g. repl.it

Do you happen to have any issues/discussions where people have reported this for other apps? I am trying to think if it's a well known issue or if there is a simple fix.

Thanks for the update. I will keep looking into this.

I can't make this happen in BrowerStack or locally. Gonna close it for now until I hear about more people running into it.
