描述

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

研究方向
Investigate how xterm.js handles keydown events, specifically for modifier keys like AltGr. The bug occurs only with the tilde character on Spanish keyboards, suggesting an issue in the key mapping or event propagation. Look at the source code for key input handling in xterm.js (likely in xterm.js/src/InputHandler.ts or similar). Compare with how other terminals like Hyper (which uses xterm.js) also exhibit the bug, indicating it's an xterm.js issue. Review the original vscode issue (#108077) for additional context and potential solutions.
