Oh, right. Thanks, Karl. I'll write myself a little note. :-)
Cheers,

I think that you are looking at the vector font encodings and trying to
apply them to TrueType fonts.
So, you can go one way or the other:
TrueType:
text = Obj_New('IDLgrText', ENABLE_FORMATTING=1, $
"(!10W!X) Greek Symbol Omega", color=[0,0,128])
XObjView, text
Hershey vector fonts:
oFont = OBJ_NEW('IDLgrFont', 'Hershey')
xobjview, obj_new('idlgrtext', '(!4!Z(58)!X) Greek Symbol Omega',
FONT=oFont, /ENABLE_FORMATTING)

Yes, I did get something like this working. What I couldn't
figure out how to do (and I think this is what the original
poster wanted) was how to get Greek symbols into his code.
For example, I tried this:
text = Obj_New('IDLgrText', ENABLE_FORMATTING=1, $
"(!4!z(88)!X) Greek Symbol Omega", color=[0,0,128])
XObjView, text
Maybe I don't know how to read the octal table. But I see
Font 4, the omega sign is 12x plus 10 octal is:
IDL> Print, "120
88
Why doesn't this work?
Cheers,
David

This example combines the two using object graphics:
IDL> oText = OBJ_NEW('IDLgrText', "I will !6do!X it ma!Z('F1'x)ana",
/ENABLE_FORMATTING)
IDL> xobjview, oText
!6 switches to complex roman and !X gets you back to the entry font.

Typically, you access these character glyphs via their Unicode
value. For example, you are talking about tomorrow:
XYOUTS, 0.5, 0,5, Align=0.5, "I will do it ma!Z('F1'x)ana", $
Charsize=3, Normal=1

I don't know if this is possible. All of my experiments
have turned out negatively. :-(
Surely, there must be *some* way to do this! Karl!?

The following doesn't exactly answer either of your questions, but I
suggest you set the ENABLE_FORMATTING property on your IDLgrText object,
then read the documentation section entitled "Fonts/Embedded Formatting
Codes"
