On Windows the path separator is U+005c, it's only a backslash in most codepages, but not all: https://devblogs.microsoft.com/oldnewthing/20051014-20/?p=33... which links to a dead link; copy here http://archives.miloush.net/michkap/archive/2005/09/17/46994...

That doesn't change just because Unicode renders individual codepages obsolete, it's now special-cased into Windows that Japanese and Korean situations display U+005c as a currency symbol instead of a backslash.

There's also [System.IO.Path]::AltDirectorySeparatorChar which is `/` because Windows is often fine with / as a path separator as well.
