[PATCH 05/11] vt: update ucs_width.c using gen_ucs_width.py

Nicolas Pitre
2025-04-10T01:19:03Z

From: Nicolas Pitre <npitre@baylibre.com>

This replaces ucs_width.c with the code generated by gen_ucs_width.py
providing comprehensive tables for double-width and zero-width Unicode
code points. Also make ucs_is_zero_width() effective.

Note: scripts/checkpatch.pl complains about "... exceeds 100 columns".
Please ignore.
