Scandinavian keyboard layout can't handle input tilde (~)

[ixrock]

To type ~ with Finnish/Swedish keyboard I have to press hotkey alt+^:

After that it shows something similar to ~ but right after when I press any other character (except Enter) it will erase "pre-tilde" symbol. Press Enter "converts" to normal ~ and nothing more (without real Enter).

I checked how this works with vanilla JS and it seems something wrong at browser-level:

Is it fixable? Wdyt?

@Tyriar how xterm related to vscode?

[Tyriar]

vscode uses xterm, that's the issue that's been reported over there.

Terminus has the same issue: Eugeny/tabby#768
This isn't limited to Scandinavian keyboards. At least French and Spanish are affected too (any layout with the AltGr key and 2 steps accents feature I presume).

It's still possible to catch ~ with InputEvent:

I'm not sure if this ever worked if InputEvent fixes the problem, sounds like it might be the same root cause as #469 and needs us to move input handling over to input instead of the key events.

@Tyriar Using only InputEvent for sure not enough. Its evt.data just contains current value-string for input/textarea and nothing about pressed keys, etc. I just thought it might help to fix this issue combined with normal KeyboardEvent.

I'm having the same issue in Fluent Terminal.
I can't type ~, it shows Þ instead. My keyboard is PT-BR (with the AltGr key), but if I change the layout to US, I can type ~ using the ' key.

Until this issue will be fixed I suggest using workaround from here
