Let's illustrate this with an example. I have a path type X that stores 
UTF-8 and a path type Y that stores Shift-JIS, both are instantiations of 
basic_path<char, Tr> for some TrX and TrY.

How do you envision the conversion being called (a converting constructor, 
explicit, implicit, a dedicated function) and which of TrX and TrY will be 
used for the conversion?
