2.6.x and fonts with accents

[Sterling Sympatico]

Hi all,

I just upgraded from 2.4.5 to 2.6.3 in Debian "testing" and converted my
few meager scores.  I noticed that (and expected) that the fonts would
be handled differently but am not sure of how to put simple accents and
such in titles and markup.  I want a ~ over an "n" in the title -
"Habenera".

I was using Hab\~nera but that no longer works.  Do I need to define
some sort of "pango" option in the score headers somewhere?

Thanks in advance,

Sterling MacNay
