It shows UTF-8. Keep in mind that utf16-le/be with no bom work fine. It's only
utf-8 that's broken.

No, it wasn't. It's fresh from your tarball. Forcing it to open as ANSI gives:
«utf8 -bom ßłøþ»

which looks a lot like wine, except for 'Ÿ'.

Perhaps you need to use the IsTextUnicode() function here...
