Torrence does not appear to be on either my Linux or Mac machines.)

The version of tex2IDL() I am looking at has
the Sun symbol, but as a Unicode value. The
real problem is that IDL does not come with
an installed Unicode font that can be used.
You have to go looking for one. Then you have
to install it in the IDL distribution, modify
the ttfont.map file to locate it, etc., etc.

It is *slightly* easier in Windows, because you
can use the fonts that are installed in the normal
Windows/fonts directory just by naming them. But,
even then, it is difficult to get the thing working
everywhere. (I just tried adding the Sun and Earth
symbol the the Greek program I have.)

The problem there is that you have to "install"
the true-type Unicode font you want to use:

Device, Set_Font='Arial Unicode MS', /TT_Font

But this doesn't "transfer" to the PostScript device.
So, even if you get it working on your computer, there
is no guarantee it is going to work in PostScript. You
have to Set_Plot to PostScript, then issue the *same*
Device command as above, and THEN it works everywhere.

It just seems too darn complicated to be useful.

Cheers,

David
