Extended ASCII character in MATLAB plot label/title

Question

I need to put word "naïve" on a plot, and save it as PNG and PDF. Sometime it's in a title, or in tick label. Whatever I've tried I always get right arrow symbol (png) or empty space (pdf) instead of the ï character.

I've looked into functions native2unicode and unicode2native, but they seems to be only for file input/output.

I cannot believe this task is so difficult in MATLAB.

I'm using MATLAB 2012b undier Windows 7.

The symbol ï has ascii code 0239, or hex 0xEF. MATLAB shows it in console if it's entered with Alt-0239, but displays as empty square.

MATLAB returns 26 as character's code:

>> int32('Naïve')
ans =
          78          97          26         118         101

This symbol isn't present in MATLAB's TeX Character Sequence Table.

Answer 1

This must work:

X=rand(10,1)
Y=rand(10,1)
plot(X,Y)
title('na\"{i}ve','interpreter','latex');

If you need you can also change font and size , etc.

By the way, take a look at
