how to use a postscript font in a .ly file?

[Eduardo Vieira]

Hello friends,

I'm wondering how can I use a PostScript font in a text markup for my score.
Here are my settings: Windows ME, Lilypond 2.7.39, the installed font:
Isabella (c:\psfonts\iz______.PFB).
I saw in the regression tests an example (font-postcript.ly), but I can't
figure out myself how to adpt it, or if it's possible to do it in Windows
platform.

Thank you,

Eduardo
