accents in a plot

[youtwistedmymelonman]

Hello,

How could I use special characters (like accents) in a plot?
When I use an accent in xlabel, for example, I get some weird characters or garbage instead of the accent I was trying to type.
Am I doing something wrong? Is there any workaround to this?
In Octave 2.1.73 I was using
__gnuplot_set__ encoding iso_8859_15
as a workaround and it worked pretty well. But now this __whatever__ commands seem to be deprecated...

I'm using Octave 3.02 and my system default encoding is UTF8.

Best regards.
