Sometimes robobrwser get wrong encoding for my page. I know that BeautifulSoup supports manual encoding definition can I set up encoding manually and passed it to BeautifullSoup? In my case it founds windows-1252 instead of UTF-8

And if I use just BeautifullSoup with requests - it works fine

```
>>> from bs4 import BeautifulSoup
>>> from robobrowser import RoboBrowser
>>> import requests
>>> url = 'http://10x10.com.ua/televizor-bravis-led-32d3000-smart-t2-black-v-dnepropetrovske.html'
>>> rb = RoboBrowser(parser='lxml')
>>> rb.open(url)
>>> rb.select('.product-name h1').pop()

>>> bs.select('.product-name h1').pop()
