You are right.  I thought I could convert simple strings by hand, but
obviously I didn't select the proper UTF-8 encoding (in some cases).
I believe you catched all errors.  Since those examples test whether
the application uses a validating UTF-8 decoder, I will keep those
examples modified to result in an UTF-8 decoding error.
Non-validating UTF-8 decoders should produce the correct Unicode code
point for those UTF-8 encodings though.
