Hi David,
thanks for the answer, although i had already checked there (yours is
mostly the first place i always check to solve my idl doubts). However
this time it is not the case, i already use the !9 + !X embedded
formating code, or !M for just one character without trouble on
screen.
The case is that iplot uses TrueType by default, and PS uses TrueType
too, it should export just fine. And in fact it does, in Linux and
WinXP, but not on my iMac OSX10.6 (in fact it used to do it just fine
with OSX10.5). I've also tried in a colleague's MacBookPro and it
happens to her too.
Hope to get some fix soon, otherwise i'll have to use WinXP to
generate the graphs, and i'd hate that.
With respect to pfp's answer. I was not aware of the isave function in
IDL 7.1, since we just have 6.5 and 7.0 versions... so my question was
addressed to the misterious way of programmatically export to EPS.
However, i've already found someone has written such a function:

Thanks again

I don't have a Mac, but if someone wanted to help
me out, I've put a new version of my Greek program
here:
http://www.dfanning.com/misc/greek.pro
If you set the UNICODE keyword, the program will now
return the unicode value for the Greek letter used in
the Apple Symbol font distributed with MacOSX 10.1
and higher. This *should* allow Macs to produce
PostScript output with Greek symbols correctly.
IDL> XYOuts, 0.5, 0.5, /Normal, Align=0.5, $
'Greek Letter Zeta ' + Greek('Zeta', /UNICODE), Font=1
Thanks,
David
