… a wide build (pythonGH-153863) On a wide build, winch() returns the low 8 bits of the character's code point with no locale conversion, so inch()/mvinch() disagreed with instr() for a non-ASCII character of an 8-bit locale ('€' under ISO-8859-15 gave 0xAC instead of 0xA4). Re-encode the cell to its locale byte via wctob(), as ncurses does for getbkgd(). (cherry picked from commit a83aaa9) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Manual backport of #153863.
