To put it another way, Windows allows characters that are not part of Unicode to be used to name files. If we restrict our character set for filenames to Unicode-only, we will not be able to open those files. That problem is real.
That does not mean it's a problem we need to solve. If you make it use to create filenames containing unpaired surrogates, that just means you make it easy to files with garbage filenames. I don't see that as a feature. Any such filenames are presumably unintentional and due to bugs. We don't need a standard Scheme API for dealing with those bugs, just like we don't need a standard Scheme API for editing the registry. -- --Per Bothner per@xxxxxxxxxxx http://per.bothner.com/
