Document Android backspace issue

[jsjoeio]

We need to indicate in the Termux docs there are known issues with the backspace key on Android (using on-screen keyboard).

See comment

Possibly:

• add new docs/termux.md file and add there.

Backspace works if you start backspacing "in the middle" of the word you wanna delete, but it crashes code-server(? Proof here: https://youtu.be/WOGQubsOjoo

Argh, well at least we know there is a workaround.

@leKamikaze1 do you know if the issue occurs with a separate bluetooth keyboard? I can try testing too. Wondering if this is specific to the on-screen keyboard.

Sadly, I never had a Bluetooth keyboard In my life, so its pretty impossible for me to test that

[jsjoeio]

No worries at all. I have one lying around somewhere so I can test!

@jsjoeio Found something?

[jsjoeio]

I finally got around to testing - it works with a bluetooth keyboard! No backspace issues 😄

Well, that's great. So, the issue is on Android's on-screen keyboard? Not sure what would cause it 🤔

[jsjoeio]

It has to do with the way xterm.js is handling the input for on-screen keyboards I'm guessing:

Pulled from comment

• upstream: Issues with Backspace in Codespaces on Android (Surface Duo)
• underlying issue: Support mobile platforms

Any news? Working solution?
Backspace working, but can't delete special characters

[jsjoeio]

Unfortunately, no :/ this is upstream and out of our control to fix. Only working solution I know of is to use an external keyboard.

Thanks for linking that @nikey02 ! Looks like that was part of vscode 1.55.2, which we upgraded to in #3085 which means...hopefully this isn't an issue in our next release 🤞
