VS Code issue: https://github.com/microsoft/vscode/issues/172536

re https://github.com/microsoft/vscode/issues/168804

  • mac
  • open text editor
  • press and hold e
  • and e is inserted and get a picker for its variants like è, é, etc
  • open a terminal
  • press and hold e
  • 😕 many e are inserted
  • 😕 the variant picker shows but at a "random" location
  • 😕 the variant picker doesn't work, e.g pressing 2 doesn't replace the typed character with that variant

研究方向
Investigate the input handling in xterm.js, particularly the key event processing for macOS. The issue is that pressing and holding a key should show a character picker (like è, é) but instead multiple 'e' characters are inserted and the picker appears at random locations. Look at the KeyboardEvent handling in the terminal's input layer and compare with VS Code's own input behavior. Check the referenced VS Code issue #172536 for similar context. The fix may involve intercepting the beforeinput or keydown events differently for macOS.
