How about pasting in the micro symbol?
123×10!u5!n µ
Then it seems to work with isolatin1=true. The only problem is that it
doesn't use the symbol font, so it looks a bit different.
I was able to see the micro character by doing the following:
print,string(bindgen(128)+128b)
-Chris

Well, yes, I have the character in my iTool now. But I also have a
"micro" symbol in there (using "!mm" in the annotation). Now if I export
the plot to EPS, I have either the "times" but not the micro in there
(when setting isolatin1 = true), or vice versa (isolatin1 = false).
I guess I'm giving up and fixing my labels in Illustrator. That always
works (while blowing up the file size by a factor of 50).
Cheers,
Benjamin

Sorry, this came in after I responded to you.
Well, "nice" and "easy" and "iTools" are three words you
don't often see in the same sentence! ;-)
I would think there is only the hard way here. :-)

You need to know what the "string" value of your octal
number is. In the case of the epsilon:
IDL> print, string("145B)
e
So, that is why I can insert !9e!x into the title
string and get it to show up as an epsilon on the
display.
I presume you could do this programmatically, although
I don't have a clue how, by fishing out your axis or
font object (whatever you are trying to change) and
getting the text, manipulating that (you *could* use
your STRING() function now), and putting it back.
I just showed you how to do it with the property sheets.
Cheers,
David

Yes, I've used that before. However, in that case the special character
is part of the symbol font and corresponds to the letter "e" in the
normal font (Helvetica). In my case, the special character is in the
Helvetica font already, so I shouldn't even have to change fonts, but I
just don't know how to produce that character (since the keyboard
doesn't have a key for it) ...
What would probably work is to find the identifier of that annotation
and modify it programmatically (from the command line) using the
string() function. But it would be nice if there was an easy thing I
could type into the property sheet.

Yes, but this is direct graphics. Also it uses the string() function,
which I know how to use one the command line / programmatically, but I
don't know how to use it in the graphical interface of iTools. If I just
type string(), the string "string()" is added in my annotation ...

Well, I didn't know about that article. Neat. :-)
Here is what I just tried, which seemed to work.
I started an ISurface plot like this:
IDL> iSurface, Loaddata(2), XTitle='This is a title'
Then, I selected the X axis object and brought up its
property sheet. I found the Title field in this property
sheet and changed the title to this:
This is a title !9e!x and this is more title
When I hit the carriage return, the epsilon symbol was
in the title!
Cheers,
David

Does this work:
IDL> window
IDL> x="327B
IDL> xyouts, 0.5,0.5,string(x),/norm,charsize=6
?

Yes, that works. In fact, now that I look at the font table again (Help
index -> TrueType fonts -> samples -- thanks to David for pointing us
there on http://www.dfanning.com/ographics_tips/greek.html) I see the
micro symbol in the Helvetica font at position 265 (octal). I had looked
for that yesterday but somehow missed it.
Since it is part of the Helvetica font, it looks even better than the
character from the symbol font.
Thanks a lot,
Benjamin
