Actually, the character is the same and has always been shown as a left
arrow or as an underscore depending on what font you are using (as
copy/pasting some code from a browser to this window, which is also in
Squeak but uses a different font, will show). So the way to "fix" this
is to go to background menu and play around with "appearence..." -->
"system fonts..." and select one of the patched fonts for Shout to use
(if that is possible - I have not tried it).

About the general question, while I am very much in favor of moving
beyond ASCII-1963 draft to the ASCII-1967 final standard, I would really
like for us to go even further to Unicode so we can have left arrows in
our code without messing up underscores. This change will cause
backwards compatibility problems, however, and so only should be done as
part of a larger move to new image/source formats.
