in the SQL parser. Various backslash escapes and quote-quote escaped sequences are covered in combination with single and multi-byte characters. This is especially important for the character sets that can have 0x5C as the second byte in a multi-byte character (big5, cp932, gbk, sjis). swe7 is also a special character set, because in swe7 0x5C is used for both escape character and for "LATIN CAPITAL LETTER O WITH DIAERESIS".
