Describe the bug

Unexpected horizontal bumps on vertical cursor movement with not-narrow characters and combined characters

For the term "not-narrow", this issue mainly describes about CJK "Wide" characters and "Fullwidth variant" like Fullwidth Latin, etc.
But it seems that the tab characters also trigger this buggy behavior. #8108

  Each line of string is consist of characters used in

  • English, with full-width latin characters
  • English, with half-width latin characters
  • Japanese
  • German
  • Korean, with Hangul Syllables Unicode block characters
  • Korean, with Hangul Jamo Unicode block characters
  • Thai
  • Mandarin, simplified
  • Mandarin, traditional

  respectively.
  Note that for Thai and Hangul Jamo characters, some groups of Unicode characters can be combined to compose single displayed character.

• Fonts used to create sample images
  NeoDunggeunmo for latin and korean glyph
  GNU Unifont for fallback.
  Both are 8x16 grid bitmap based monospace-ish font, so glyphs are perfectly aligned.
  (I think this will be reproducible just with Unifont.)

• Steps

  1. Click left side of the first occuring of full-width character ａ to put cursor.
  2. Press k/j or arrow up/down to move cursor up and down.

Expected behavior

Cursor should move vertically, without horizontal movement, follwing marked line on image.

Recorded on VSCode with extensions disabled.
Note that VSCode also has problem with Hangul Jamo Characters. microsoft/vscode#207794

Screenshots

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.27.2
• VSCode version: 1.87.2
• OS: Windows 11 23H2 22631.3296

Additional context

Foldfix partially fix this bug, but as you know, there's side effects.
Also cursor drifts toward left on unaligned part unlike vanilla VSCode.
