Re: strutils.toLower deprecation?

I think that a string should be UTF8 by default. There is no reason functions 
shouldn't work with utf8, unless it really is performance critical. And string 
manipulation is rarely the performance critical part of the code. I can imagine 
that it could be hard to implement everything in Nim could be a lot of work, 
but I think the goal should be there.
