patch 9.1.0132: "C" doesn't include composing chars with 'virtualedit' Commit: https://github.com/vim/vim/commit/048761bcd40ec630fd3e039f0066cf4e484ceabd Author: zeertzjq <zeertzjq@outlook.com> Date: Sat Feb 24 14:21:39 2024 +0100 patch 9.1.0132: "C" doesn't include composing chars with 'virtualedit' Problem: using "C" and 've=all' set, doesn't include composing chars when changing a line, keeps the composing chars for whatever is typed afterwards. Solution: Use mb_head_off() and mb_ptr2len() instead of mb_tail_off(). (zeertzjq) closes: #14083 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
