patch 9.1.0199: Not enough tests for the slice() function Commit: https://github.com/vim/vim/commit/ad38769030b5fa86aa0e8f1f0b4266690dfad4c9 Author: zeertzjq <zeertzjq@outlook.com> Date: Sat Mar 23 08:23:48 2024 +0100 patch 9.1.0199: Not enough tests for the slice() function Problem: Not enough tests for the slice() function. Solution: Test with multibyte chars, and in both Legacy and Vim9 script. Update docs to be clearer about how it treats composing chars.
