Hi,
i'm generating a bunch of graphs in which the title includes greek
symbols (using the !9 + !X way).
They show correctly, but when i export to EPS in vector format the
greek symbols appear empty. However, if i open the file with inkscape
(a vector illustration editing program) i can select and change the
type and the text is there.
This behavior seems to happen only under OSX (my version is Snow
Leopard), it also happens with different versions of IDL (i've tryed
6.3 and 7.0).
My guess is that there is some kind of font conflict, but don't know
how to solve it.
Any hints?
by the way, I'd also like to know how can i programmatically export
the iplot to EPS in VECTOR form. I just found how to do it in bitmap
(which incomprehensibly is the default format).
Thank you in advance for the response!

Yes, this is exactly the problem. The Symbol font present on
almost all computers does not support Unicode values. But
Apple decided in MacOS 10.1 to a supply a Symbol font that
*does* use Unicode values, thus breaking all the code previously
written in the world that takes advantage of Symbol fonts. :-)
I have a program that can return Unicode values for Greek
letters (which presumably would work in any font that supported
such characters), but I have had no luck wrapping the Unicode
characters in the Symbol font for Mac computers. Presumably
because I don't have one to experiment with. Or maybe because
Apple is perverse enough to make it impossible to access without
writing an Apple App with the proper software. ;-)
Cheers,
David

I'm a bit fuzzy on this, but I seem to recall that the Symbol font was
a bit of an "oddball" in that it did not include any Unicode-to-glyph
translation tables. That is, it could only handle ASCII 7-bit
character encodings. Anyway, there was certainly something less
capable about this particular font, compared to the others.

OK, now I'm totally confused. :-)
Just one more test, if you don't mind. I presume you might
get the right symbol if you DON'T use the UNICODE keyword.
Which would probably mean you are using the "normal" Symbol
font. Perhaps the one that comes with IDL. Humm. Maybe
to get the Apple Symbol font you have to use FONT=0.
Just don't know. Too much confusion. Why do you suppose
Apple would do this? They are acting more and more like
Microsoft by the day. :-)
Cheers,
David

I get the some result:
http://michaelgalloy.com/wp-content/uploads/2010/06/greek.ps
The code I used:
IDL> set_plot, 'ps'
IDL> device, filename='greek.ps'
IDL> XYOuts, 0.5, 0.5, /Normal, Align=0.5, 'Greek Letter Zeta ' +
Greek('Zeta', /UNICODE), Font=1
% Compiled module: GREEK.
IDL> device, /close
IDL> set_plot, 'x'

Did not work for me:

Do I need to do some setup before I run the line above?

Humm. No one with a Mac interested in this?
OK, I'll move on to other things. :-)
