Oh, I see the problem: you forgot to convert " to a backslash sequence.

It would probably also be wise to convert anything >= 128 to a backslash
sequence, so as to avoid any possible problems with multibyte character
encodings.  You wouldn't see this issue in a SQL_ASCII database, but I
suspect it would rise up to bite you with other encoding settings.
