Description

Description

When typing Korean in Typing Mode (pressing 'T'), the characters do not combine properly. Instead, they are separated into individual consonants and vowels (a known as IME composition issue).

Current Behavior

When typing Korean characters, they are not composed together. Instead, they are rendered as separated individual consonants and vowels on the screen.

  • For example, typing "가나다" results in "ㄱ ㅏ ㄴ ㅏ ㄷ ㅏ"
Expected Behavior

Korean characters should be correctly composed and combined according to the macOS standard IME behavior.

Steps to Reproduce
  1. Enter Drawing mode (Control+2).
  2. Press T to enter Typing Mode.
  3. Change the macOS input source to Korean.
  4. Type "가나다"
  5. Observe the separated characters instead of combined ones.
Product Version

Research direction

Start by locating the Typing Mode entry point reached by T after entering Drawing mode, then reproduce the issue with the macOS Korean input source and "가나다". Done means Korean syllables are composed rather than displayed as separate consonants and vowels.
