Steps to Reproduce:

  1. Turn on U.S. International keyboard in Windows.
  2. Open file in Visual Studio Code.
  3. Type AltGr+u

Reproduces without extensions: No

Issue does NOT occur without extensions. However searching keybindings for Alt+u does not find anything.

Issue does NOT occur for the other Spanish characters (¡¿ÁáÉéÍíÑñÓóÚÜü), just ú when entered as AltGr+u.

Issue does NOT occur when entering ú via '+u.
