Whatever you type.

This demonstrates that in Python 3.3, u'a' gives a string equal to 'a'.

Since you typed the letter a, r1 is the string "a" (a single character).

Since you typed four characters, namely lowercase u, single quote, 
lowercase a, single quote, r2 is the string "u'a'" (four characters).

If you call print(r1) and print(r2), that will show you what they hold. 
If in doubt, calling print(repr(r1)) will show extra information about 
the object.
