I just tried String#encode with no parameter, but I was hoping to just be  
able to say:

	return str.encode

to return a string from a method in the default_internal encoding if it is  
set. Unfortunately, unlike my suggested implementation, it raises an  
exception when default_internal is not set, so I have to say:

	return Encoding.default_internal ? str.encode : str

which isn't really much neater than what I had before:

	return Encoding.default_internal ? str.encode(Encoding.default_internal)  
: str

I guess I can either write my own encode_internal method to handle this,  
but I think it is universally useful for libraries which handle strings,  
where default_internal may or may not be set.

Cheers
