[Xastir] Font warning message

[Richard Polivka, N6NKO]

I am running the latest devel release here from a console window and I 
am getting this message that is font related:

Warning:
    Name: create_appshell text_output2
    Class: XmTextField
    Character '\260' not supported in font.  Discarded.

I am sure that this message has been there for some time but I never 
realized it. I know that it is font related and it is looking for 
something.
What is missing or needs to be done?
