hmmm.... I would try googling it. I think the language is HTML. My guess would be to try sequential double/single quotes (example:
I said ""hello"" to Mr. Bean instead of
I said "hello" to Mr. Bean).
If that doesn't work, you could try this:
double quote:
"
single quote:
I don't know for sure that either of those will work though but I googled newline character and guessed what language they used to write the page to figure out what might give me a newline character. I think something similar should work to figure out quotes and apostrophes. Hope that helps!
EDIT: SDN uses HTML - Go here for codes:
