I can update patch I initially attached to: For btowc, check for value to be in range [0,255] instead of [0,127].
For wctob, remove range check and use code page 20127 (ASCII) for conversion (so it matches CRT's best-fit behavior). - Kirill Makurin ________________________________ From: LIU Hao Sent: Thursday, June 5, 2025 1:04 PM To: Kirill Makurin; mingw-w64-public@lists.sourceforge.net Subject: Re: [Mingw-w64-public] Inconsistent behavior of btowc with "C" locale 在 2025-6-3 19:40, Kirill Makurin 写道: > I think glibc just did not implement this behavior yet.
