…n a wide build (pythonGH-153865) On a wide build, winsch() does not locale-decode a byte above 127, unlike waddch(), so insch() inserted '¤' (U+00A4) instead of '€' for byte 0xA4 under ISO-8859-15. Decode the byte with btowc() and insert it as a wide character, like addch(). (cherry picked from commit 223cbff) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Manual backport of #153865.
3.15 predates the 3.16
complexcharrefactor, so the fix adds a wide-character path to 3.15's simplerinsch()using its existingaddch()idiom (setcchar(..., PAIR_NUMBER(...), NULL)+wins_wch/mvwins_wch).Verified on a wide (
