You can't initialize dictionaries that way, its simply the wrong syntax. Since you want to use unicode characters as keys, your keys need to be strings.
This thing here should do what you want:
dictionary = {'a':'alpha', 'b':'b', ',':'=', "'":'}' }
Notice how all the keys are strings. If you set up the dictionary in this way you need to use the colon instead of the equal sign to assign values to keys.
