Issue Type: Bug

Hello,

I have a keyboard with spanish layout.

When typing the ~ character (which in my case is Alt Gr + 4) in the terminal 4~ is printed. This only happens when I use the integrated terminal in vscode, and only with the ~, for example with the # which is Alt Gr + 3 does not happen

error3 error4

For example these examples are using windows terminal & cmd

@Tyriar Is this related to #3129?

Tyriar commented 3 years ago

VS Code Insiders is based on Chromium 83, so that doesn't align with what's said in https://github.com/xtermjs/xterm.js/issues/3129 about Chrome 85 working.

This has happened to me for a while now, I think that this has always happened

I have been investigating the issue, and I think that has to do with how it handled at the SO level. The symbol, in the Spanish layout, is treated like the accent mark, you have to type any other character in order to "flush it"

For example:

In this case, I type the Alt + Ctrl + 4 nothing happens, then I press space the character ~ gets rendered on the screen And then I type Alt Gr + 4 the character 4 gets rendered then I press space and the character ~ gets rendered on the screen
