Yes, you could do it with python.
(Enable scripting in application properties)
Create a "start of layout"-event and add the following script to it:
Then, whenever you need a double quote in a string, do it like so:
-> Text: Set text to Python("doublequote()") & "seems to work" & Python("doublequote()")
I haven't tested if this will also save to a file correctly, but it should.
EDIT: I just tested the following, which set the text to "yeah" not yeah
-> Text: Set text to """" & "yeah" & """"
Looks odd, but seems to work.tulamide2012-01-05 06:45:19
