No. If you don't want white space around the returned string then there's
no reason it should be returned by the custom tag! Trim it within the tag.
Also, for maximum flexibility (and safety) you should pass in the name of
the caller variable, rather than using a predetermined name.
<cf_MyCustomTag inputstuff="48" variable="myVariable">
<cfoutput>#myVariable#</cfoutput>
Your custom tag then does something like:
<cfparam name="variable">
<!---
processing to arrive at a value within the internal variable
called 'returnvalue' ...
--->
<cfset temp = SetVariable("caller.#attributes.variable#",
Trim(returnvalue))>
