Remove the u prefix of unicode strings on error output

[jmwri]

I use unicode everywhere within my project, and this affects the output of Voluptuous' exceptions.

required key not provided @ data[u'site_user_id']

Is it possible to remove the unicode prefix?

Can you please share your schema? Since according to this test, it shouldn't be there at the first place.

Changing the test to the following is what I am doing:

schema = Schema({Required(u'q'): 1})

Notice the unicode dict key. From what I have seen it is best practice to ensure all strings are unicode strings, so I only use unicode literals in my project.

Umm.. Ok. Can you create a PR corresponding to it? You will have to do modifications in schema_builder.py for supporting this feature.

[jmwri]

I will investigate and ask if I need any help. Thanks :)!

Sorry @tusharmakkar08, would you be able to briefly explain the flow? I'm not really reading this too well.

@jmwri : Ok.

Start from Line 147 where Schema class is defined which calls _compile in Line 219 and depending on the type of schema appropriate function is called. For your scenario, you can focus on self._compile_dict and self. _compile_object. These functions further call self. _compile_mapping at Line 239. Here we call as a closure validate_mapping in Line 262, where the final output is yielded. So you need to essentially make changes in self._compile_mapping function.

@tusharmakkar08 I have made changes to account for unicode Marker keys and plain text keys too. Are there any other types of keys?
