It's the exact same thing. They're a backslash followed by a letter U.
However, if your stdin is set to (say) UTF-8, then bytes that
represent non-ASCII characters will be correctly translated,
eliminating any need for code-style escapes.

Allowing your users to put escaped Unicode characters into their input
opens up a huge morass - do they have to double every backslash? what
if they actually wanted "\", "u", etc? etc? etc?
