Bitcoin URL label encoding

[playtin]

In https://en.bitcoin.it/wiki/URI_Scheme is stated:

Characters must be URI encoded properly.

However, this does not seem to work.
Say we need to label this "pos#1"
bitcoin:1PuR9qRJ7BsyeiZPn4EjbG5oH94nkz9you?label=pos#1 results in "pos"
bitcoin:1PuR9qRJ7BsyeiZPn4EjbG5oH94nkz9you?label=pos%231 results in "pos%231"
Does anybody know how to encode a label?

You need to decode the encoded version afterwards to use it as normal text

I just tried it in MultiBit.

Type in a label "pos#1".
If you scan the QR code generated you get "... &label=pos%231"

Copy and paste the QR code to another wallet and your label gets decoded back to "pos#1"

It is the same with foreign languages.
Chinese label of "你好!" ("ni hao !" = "Hello!") => &label=%E4%BD%A0%E5%A5%BD%21

(the unicode of "ni hao !" I think)

=> 你好! after decoding

My point was that apparently Bitcoin-QT does not do this.
