I'm not following or finding what you found.  I've modified my __axis_label__.m 
file per the patch and everything works fine.  For example, I try

plot([0:50]);
A = {"testing", "1^2_3"};
title(A);
xlabel(A);
ylabel(A);

and the result looks just the way I think it should look.  I know that your new code is 
being executed because I took away a semicolon so that I could see the resulting 
"txt".

Doing a

set(1, "__plot_stream__", 1);

shows the gnuplot stream in which I see the following:

set title "address@hidden" font "Helvetica,10" enhanced;

This all looks quite good to me.  Could you give a series of commands in which it fails?  Try the 
"set(1, "__plot_stream__", 1);" to pinpoint where the extraneous "}" is coming 
from.

Well, I guess I should say that I've tried it with the x11 terminal.  Perhaps 
it is a gnuplot bug in another terminal driver.
