No trick that I know of.  Gnuplot would have to contain a complete
TeX parser in order to figure out how many printed characters 
result from a TeX command sequence.

I'm not a big fan of the various TeX terminal types.
I'm willing to accept gnuplot's own "enhanced text" mode for key
entries and axis labels, and then include the resulting stand-alone
png or eps file in a TeX document.  But I know the mis-match in
fonts between the gnuplot text and the document text bothers
some people.
