To handle full width character correctly (as VSCode does and neovim/vim) on jk motions
Which issue(s) this PR fixes
This is to address issue: #4096
Special notes for your reviewer:
The code is WIP (needs cleaning after making sure things work), the changes broke the logic of

If anybody want to contribute to the PR, please do so, or at least share your ideas ❤️.
