Although custom fonts are useful and all that, I still say Autodesk should make changes to their RomanS font and ADD new symbols! Don't replace anything that exists already, just change the I's, and O's, etc. and add more special characters!
That's my argh for the day... so far.
And heck, our AutoCAD 2008 just arrived today, so maybe we'll find that the DID update it.. ( Notice I'm not holding my breath )
