From 3ed40b9f87c2d855fccd9a4bb6bce7e980799abe Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Thu, 19 Dec 2024 19:36:15 +0200 Subject: [PATCH] Windows: Revert the setlocale(LC_ALL, ".UTF8") documentation Only leave the FindFileFirstA() notes from 20dfca81, reverting the incorrect setlocale() notes. On Windows, Gettext's overrides setlocale() with libintl_setlocale() wrapper. I hadn't noticed this, and thus my conclusions were wrong.
