Your interpretation of my question was correct.  It was just wishful
thinking on my part that you could somehow use some special character or
something to get the scenario that I was describing to work.  I figured out
as much by looking through the source code.  Thank you anyway for the
response.

I don't understand the question.  If you're trying to split a string based
on a delimiting pattern, you don't have to do anything special to the input
string.  If the input string you are splitting contains occurrences of the
delimiting pattern that you don't want to treat as a delimiter, then
you just have to come up with a pattern that more accurately reflects
your splitting criteria.  If the case is sufficiently complex that it
cannot be handled by a single pattern, then you can't use split and
have to write a lexer (i.e., tokenizer) and extract the tokens with
some extra code.  A while loop with a couple of pattern matching tests
will do the trick.
