How to reliably guess the encoding between MacRoman, CP1252, Latin1, UTF-8, and ASCII
...e ·•–é°®’èö—. Based on this fact,
The bytes 0x92, 0x95, 0x96, 0x97, 0xAE, 0xB0, 0xB7, 0xE8, 0xE9, or 0xF6 suggest windows-1252.
The bytes 0x8E, 0x8F, 0x9A, 0xA1, 0xA5, 0xA8, 0xD0, 0xD1, 0xD5, or 0xE1 suggest MacRoman.
Count up the cp1252-suggesting bytes and the MacRoman-suggestin...
