[antlr-interest] Problem parsing unit symbols

[Mark van Assem]

Hi,

Correct, I wasn't precise. I have to parse text obtained from Excel 
files made by people, who will probably use many variants of writing the 
same thing down, e.g. "Å" "Ångstrom" "ångström" etcetera.

My bad, I stripped the wrong part of my original file. Thanks for 
spotting this.

How can I see that such a thing is present in a file? Is there an editor 
or viewer or something like that that can assist me in this?

Many thanks,
Mark.
