Fix for traceback when we encounter non-utf8 characters in diff

Browse source 
We can diff non-utf8 files (as part of copy, for instance) but when we
try to turn the bytes into text for display, the characters cause
a traceback.  Since diff output is only informational, we can replace
those problematic bytes with replacement characters.  We do not want to
do this to other fields because those fields may be used inside of the
playbook (for templating another variable or matching in a conditional).

Fixes #21803
Fixes #21804
