Re: the "Unicode Background" section

How about allowing characters to encode surrogates, but signalling an error if a surrogate is passed to string-set!

This would allow you to do what you want with characters, would allow you to deal to some degree with poorly formed strings that are imported into Scheme, but would not allow you to construct poorly-formed strings within Scheme.
