Scheme UTF-8 Survey

This is a set of examples of UTF-8 in Scheme that test what happens when an implementation gets an invalid UTF-8 string.

This survey works by executing a battery of UTF-8 decoding tests.

Note that in R7RS, passing bad UTF-8 to utf8->string is "an error": the implementation can do anything. The tests here assume that the implementation either raises an exception or returns some valid string data.
