[issue4540] typo in a module describes utf-8 as uft-8

[Jervis Whitley]

I can still reproduce on py3

>>> help("modules anything")

Traceback (most recent call last):
...

This patch works (on Py3.1a1). 


Amaury, are you still o.k with catching Exception rather

The code-refactoring does clean the structure up well.

Cheers,

Jervis
