Nice, this was long overdue, I guess.  :-)

An optional instead of keyword argument would look nicer, IMO.

I think this doesn’t leave a way to know which character in STRING could
not be converted.  It would be ideal if that information could be
provided as part of the exception, as is the case with ports (tested
with ‘test-decoding-error’ in ports.test.)

#:conversion-strategy is missing here.

bytevector->string

Not a single docstring.  Now I feel ashamed when asking Nala to add
docstrings.  ;-)

Thanks!
