The only TWO things a Tab-delimited file can't have stored as a record is a
tab and a return (newline). :-) Specifically, a tab indicates a new field,
and a newline indicates the end of the row.
These can be easily removed with a little Perl regexp such as s/\t// or
s/\n// , but I'm dangerous with Perl regexps, we'll let someone else post
better code, or you can do some studying on your own. Interchange may have
filters that handle this automatically... Check the docs.
I don't believe it is possible for a browser to enter a tab into any form
field... but that isn't a good reason not to trap it. :-)

If you want to "Reconstruct" the formatting after storing it in a
tab-delimited file, perhaps the regexp should replace the newlines with a
difficult-to-guess word or string that can be undone later. That is,
replace the newline with "!!!newline!!!" or such, so that you can later
replace that with the \n return.
Don't forget that in HTML, returns are ignored. So either display the
results within <PRE> or (as previous) replace the newlines with <BR>
