A bit of a Mystery

[Michael Doub]

Yesterday, I ported a number of geo routines in to the MasterLibrary 
that contained greek characters.  I left them in place as I thought it 
improved readability of the code as it was a lot of math.   I had no 
problems at all during the port or testing.

Today, however I started up and noticed that all of the greek characters 
were showing up as "?".   This was now the case in both the code viewer 
and in the IDE editor tabs.

Can anyone explain this to me?  I am using livecode 7.0.4 (rc2).

I have now gone back into the library and replaced all of the greek 
characters with normal variable names and retested.   The new library is 
available.
