Upgrade at least to IDL 3.0, there is now the angstrom symbol included,
see extract from the rel_note below.

IDL 3.1 $IDL_DIR/rel_note.doc:
12/1/92
Enhanced vector drawn fonts by adding the ability to handle
8 bit fonts. Added characters to Font 3, the default font,
to make it a full ISO standard 8859 Latin 1 font. Yes, this
means that there is now an Angstrom symbol!
Added the user procedures SHOWFONT to display a font, and EFONT
which is a simple widget-based font editor which allows users
to create and modify their own fonts.

Version 3.0.0
