I get around this problem with my data loads by specifying some other
arbitrary character that I know won't appear in the data as the quote
character.
Eg QUOTE E'\f' will specify form feed as the quote character, ergo any
data with double or single quotes will be loaded with those quote
characters in the string.
Something similar may help with your case.
