I guess you could just encode & escape the strings yourself. As you can see
you cannot use ' as part of a variable name nor can you use -, % etc. etc.
This might be a lil' bit time consuming but you can do something like this:
<cfset temp=Replace(temp,"'","_1","ALL")>
That would intially take care of the ' in the variable name & replace it
with _1. Then if you ever needed to replace the _1 back into a ', just
change the code on below inside the processing page. Now you could go on a
numbering scheme here for every invalid character so ! = _1, @ = _2, # = _3
so on & so forth.
