Unicode String in Python

Normal strings in Python are stored internally as 8-bit ASCII, while Unicode strings are stored as 16-bit Unicode. This allows for a more varied set of characters, including special characters from most languages in the world. I'll restrict my treatment of Unicode strings to the following −

Example

#!/usr/bin/python
print u'Hello, world!'

Output

When the above code is executed, it produces the following result −

Hello, world!

As you can see, Unicode strings use the prefix u, just as raw strings use the prefix r.
