研究方向
This bug involves incorrect vertical cursor movement (j/k) for lines containing CJK characters. The expected behavior is to match VS Code's handling after PR #44259 (https://github.com/microsoft/vscode/pull/44259). The fix likely requires modifications to the cursor movement logic in the Vim extension, possibly in files like 'src/actions/motion.ts' or 'src/common/motion/position.ts', to properly account for character width when calculating cursor positions. Investigate how VS Code's TextEditor selection computes cursor positions with double width characters and replicate that behavior in VSCodeVim.
