It's only necessary to do the normalization when creating a file-path 
from a String that the user (or application) provides. If the file-path 
is coming from the operating system, iterating over the contents of a 
directory for example, then it's in bytes and also does not require to 
be normalized.

I'm not aware of any locales on the supported platforms that would give 
us Cp037 as the default charset. The changes here are really just to us 
exercise some conformance tests with this encoding (despite the fact 
that file.encoding is meant to be a read-only property and should never 
be set on the command line).
