Yes. You need to set the ENABLE_FORMATTING property of your IDLgrText object
to 1.

Should work, but note that font-selection codes like !4 work differently in
TrueType fonts (the Object Graphics default) from the way they do in Hershey
fonts (the Direct Graphics default). E.g. !4 in Hershey gives you Simplex
Greek, but in TrueType it gives you Helvetica Bold (which probably wasn't
what you wanted). To get Greek characters in TrueType you need !9 (Symbol
font). See the table in the IDL docs under "Embedded Formatting Commands"

Thanks to Liam Gumley for helping me clarify this.
