Well, to be somewhat fair, if you do upgrade IDL text objects can now be written in TeX format off the bat.
-----%<-----
Adding Mathematical Symbols and Greek Letters to the Text String
You can add mathematical symbols and Greek letters to the text string using a TeX-like syntax. To turn on math symbols
for a text string (or a portion of a string), you need to surround that region with a pair of "$" characters. The
following tables list the symbols and letters you can embed within a text string:
[followed by a table of TeX definitions and their result]
-----%<-----
thus, $\deg$ gives one the degree symbol (ostensibly in a more "proper way" :o)

I'm working on a cgSymbol program this morning that
preserves many of these frequently-used special symbols
for display and PostScript usage. And I got a *terrific*
program from Bernat Puigdomènech that allows you to use
non-printing (e.g., foreign) characters in widget programs.
Both programs will be available soon.
Cheers,
David

I was very unhappy to find that the font tables have been eliminated.
I referenced those a LOT, and I suspect many others did too. That
would be a logical thing to re-include in a future minor version
upgrade. Also, good luck finding a decent PostScript font table
(specifically for the Symbol font) in the help. If you need any
special characters now, you'd better be a developer.

That only makes sense if IDL fully supports unicode. I guess that is
too much to ask. Then there is textoidl, which I find a whole lot
easier to work with than the font-codes, but maybe that is just me.
