Now that's some fine tagging there. It looks like Unicode processed as one-byte characters, then converted to simple ASCII. That quote-y-t-h part would be the Unicode BOM (0xFF 0xFE), which is ÿþ in the Windows-1252 codepage, and that would be converted to "yth in ASCII. And the strings are cut short because of the null-bytes following simple latin characters.
