According to the docs this method should return a str, but it returns bytes

I can see three options:
 a default encoding should be applied
 the documentation updated to make clear this returns bytes
 the method removed and just rely on the existing unpack_bytes which does what you'd expect (and in fact the two methods are aliases)

xdrlib doc seems still remain in 2.x world. 'string' is used to represent 'bytes'. And some methods' names like pack_fstring, pack_string seem not suitable in 3.x world.

The term "string" in names like "pack_string" refers to the XDR standard (RFC 1014). They have to stay, but the documentation must be updated to make clear that they work with bytes.

There's a patch for xdrlib documentation in Issue9544. Would that solve this issue?

Partially. Thank you for pointing on the predecessor Jan.
