I think it's too bad that we didn't choose delimters that had no chance of appearing in actual text. Commas are a big one, when parsing csv there's always the problem of having commas in the text of a field. One hack I have used if I don't want to delete them is to swap them for a character I imagine will never be in the text, such as | (pipe). It all could have been avoided if we had some standard delimiters that were not part of common text.
