Describe the bug

When using a CJK input method in NormalMode, an issue occurs where CJK characters are being input.

• MacOS Korean Dubeolsik (two-set) Keyboard Layout
  • h -> ㅗ
  • j -> ㅓ
  • k -> ㅏ
  • l -> ㅣ

Current Problem:
When set to Korean input method, entering h, j, k, l in normal mode writes the characters ㅗ, ㅓ, ㅏ, ㅣ to the file.

Expected:

Expected:
When set to Korean input method, entering h, j, k, l in normal mode should not write the characters ㅗ, ㅓ, ㅏ, ㅣ to the file.

• Method 1: Since these are not h, j, k, l character inputs, the cursor should not move.
• Method 2: Since these are Korean characters corresponding to h, j, k, l, the cursor should move.

In any case, characters should not be entered in normal mode, but currently Korean characters are being written to the file.

To Reproduce

1. Install Korean IME. (Korean Dubeolsik (two-set) Keyboard Layout)

• (On MacOS, use Keyboard Shortcuts > Input Sources shortcut.)

2. Enter normal mode in VSCode Vim.
3. Set up Korean input method. (On MacOS, use Keyboard Shortcuts > Input Sources shortcut.)
4. Open file, and input h, j, k, l key.
