As discussed in the original thread, Emacs uses ANSI version of Windows API to handle fonts. Strings passed to or received from APIs should be encoded in or decoded from ANSI codepage. To do that, ENCODE_SYSTEM and DECODE_SYSTEM macros are used (See src/w32font.c). It means that locale-coding-system is used around Windows font API. That works well on MinGW64, because locale-coding-system is the same with ANSI codepage. But on Cygw32, locale-coding-system is normally utf-8 and it is not ANSI codepage. This is the cause of the problem. My original post makes Emacs use ANSI codepage for Windows font API. Further discussion indicates to make Emacs on Windows use unicode API if available. But no progresss after that. -- Kazuhiro Ito
