Contains Predicate And Double Quotes

I have been searching for an escape character or a way of escaping
double quotes that are actually in a string that I am using in the
contains predicate.

Here is an example

select *
from table
where contains(field, '"he said "what is wrong", that is what he
said"')

I need the double quotes in the string because they are part of the
text. Of course, Fulltext search raises the error

Server: Msg 7631, Level 15, State 1, Line 1
Syntax error occurred near 'what is wrong", that is what he said'.
Expected ''''' in search condition '"he said "what is wrong", that is
what he said"'.

If I remove the double quotes, the search does not return the proper
results.

Thanks in advance for the help
