Every string parser I'm aware of is okay with an apostrophe inside
double quotes. Or a double quote inside apostrophe. You only run
into trouble when trying to put the same character inside the
delimiter.
But Jackie is right that the backslash is used to allow characters
that would otherwise not be permitted or have no conventional
representation (white space characters like newline or form feed are
the most common examples of this).
The problem of how to represent delimiter characters inside delimited
blocks is a very common one.
Another common solution in the case of double quotes is to transform
pairs of double quotes into a single double quote in the output. I've
also seen string parsers that will transform paired single quotes into
a double quote.
I prefer backslashes personally.
