Actually, it won't ever bother to convert them. The Windows file
system APIs are quite happy to work with forward slashes; it's only
command-line tools (which conventionally use forward slashes to
introduce options), and not all of them, which require backslashes.

You may want to consider explicitly converting them in your own code,
prior to showing a path to a human; but even back in the 1990s, it
wasn't uncommon for cross-platform programs to mix and match - for
instance, if you unzip something into C:\Foo\Bar, you'd get output
like "Inflating C:\Foo\Bar/usr/lib/whatever". I'd have no objections
to a program using forward slashes all the way.
