[mac-gs] Font problem with mac os x

[nino]

Hi,
I'm trying to use ghostscript as a process to produce pdfs on a mac os x
10.2.4 and ghostscript 7.05 and 8.00.

The problem is that accented letters (I'm European...) are not represented
correctly for all truetype fonts present in the system, including Helvetica,
Times and all other basic postscript fonts when opening the pdf with Acrobat
reader or Preview.

Notably I get very good results when I use postscript fonts available on my
os 9 environment.

Do I've to compile ghostscript with special option to have it use Truetype
fonts?

Or, do I need to change some ghostscript font definition in Fontmap or
similar? And, if yes, how to change it?
