I'm not sure why you are getting the warning. I don't see that.
However, the title command is being interpreted as "<tab>au"
To get \tau, you'll need to either ...
title ('\tau')
... or ...
title ("\\tau")
OK, the error message only occurs for the title command above, so it must be an error relating to the <tab> interpretation.
title("\\Tau") returns \Tau
title('\tau') returns "t"
title('\gamma') returns "g"
Not greek symbols but the traditional letters. A font issue maybe?
