QTextStream uses the system default locale, but this breaks in various situations: (1) It does not work on the native Windows shell (cmd.exe, Powershell), since the default Windows locale is Windows-1252, but the shell uses Windows-850. (2) It also breaks on *nix systems where the locale is Latin1 or C, which is the case for most CI systems or build servers. We allow overriding the detected codec by setting the ENCODING_OVERRIDE environment variable, but otherwise prefer Windows-850 on Windows and UTF-8 on any other system, even if LANG is set to something else. This resolves #2413
