Error using latex in function

Hello, I'm trying to use latex to insert a specific symbol using the "text" command in Matlab 2014b. The line in my function is pretty straightforward:

text(1.5,0.43,'\fontname{Lucida sans unicode}\fontsize{12}?')

(the symbol appears as a box in the Matlab editor window)

When using this line in a function, a question mark is displayed instead of the symbol. However, when using the same line from the command window the symbol appears with no problems. Finally, I tried inserting a breakpoint at this line in the function and then inserting it to the command line - and it also works fine.

Any ideas regarding how I can display the symbol without resorting to breakpoints as a way of life?

Thanks, Eitan

Is the symbol one whose Unicode position is 256 or greater? If so then you might not be able to hard-code without taking special steps to convert your MATLAB to use UTF8 .m files. Try building up a string with char() of the numeric position, such as

text(1.5, 0.43, ['\fontname{Lucida sans unicode}\fontsize{12}', char(1234)])
