LaTeX: selecting font with fontenc package

[AlephZero]

Running XeTeX from TexLive 2011 on windows, I have been using

\usepackage{fourier}

To get the Adobe Utopia font. That works fine.

For reasons irrelevant to the question, I want to use the fontenc package to select fonts. So I need to do something like

\usepackage{fontenc}
\setmainfont{ ... what goes here? }

Utopia, utopia, and Utopia-Regular don't work (lots of errors, TeX tries to build the fonts using textmf, and fails).

Searching for file names containing utopia and Fourier didn't help.

The fontenc package documentation doesn't help either - it makes the assumption that if you want to use a font, you know what it's called. WRONG!

Any suggestions?

FWIW the fontenc package itself is working - a demo file using a different font (Junicode) works fine.

I think I've answered my own question. The version of the Adobe Utopia font that is free with TeX distributions in in Postscript Type 1 format. The font handling in XeTeX and the fontenc package is meant for TrueType or OpenType fonts.

Adobe do a TrueType version of Utopia, but it's not free.

And unfortunately, converting Type 1 fonts to TrueType accurately is hard, unlike the reverse conversion.

That doesn't solve the problem, but at least it explains it.
