Prevent editable widgets from adding various characters when F1-F12 is pressed by the user.

Browse Source 
Formerly the code just casted the "ascii" value of the key event to "byte"
and thus truncating the character value. Now that would be fine, if we
would not allow values >= 256 in the ascii field, for example 322 for F8
which in turn resulted in a "B" added to the editable field. I just added
a check for the values being in the byte range before doing the cast,
which fixes this.
