Re: Magic Quotes question

["Sanjay R" <2sanjayr () gmail com>]

the reply may not be directly addressing your issues, but can give
some inkling (read from Shiflett's article)....
in case, GBK character set is involved, you can try using intelligent
encoding. In GBK, 0xbf27 is not a valid multi-byte character, but
0xbf5c is a valid one. so, what does it say? we assume that
addslashes() is being used. so, for single quotes 0x27, we will write
0xbf27. addslashes will change this to 0xbf5c27 i.e 0xbf5c and 0x27.
