Variable Width Encoding

Reports Cheng Peng Su's variable-width encoding filter evasion: a lead byte in the range 192-253 or 255 combines with a following double quote into a single multibyte character, so the quote stops terminating an attribute and the attacker stays inside the tag. Affects UTF-8, GB2312, GB18030, BIG5, EUC-KR, EUC-JP and SHIFT_JIS in Internet Explorer.
