Hi Folks,

I am trying to use the Explorer geometry API: 

   cxGeoTextDefine(text_string, X_font_name); 

to add annotation to a scene.  Specifically, I would like to use the call
to print numeric and math symbols like a temperature value followed by
a degree sign.  

The problem I am having is that the cxGeoTextDefine call only seems
to support characters with an ASCII value between 0 and 127 even if the
X font I have chosen supports characters outside this range. Unfortunately, 
some of the characters I want to use (like the degree sign) have a value 
greater than 127.

Can anyone tell me how to add annotation which includes "special symbols"
like the degree sign for instance?

Thanks for any pointers.
