By unicode character, I assume you mean non-ASCII?  All ASCII characters are 
Unicode characters.

There is a problem here.  You don't need to cat your test file to see the 
problem, just input a non-ASCII character from the keyboard, for example å.
The dock-started Emacs will not show å, it will show \345.
