Not bad! This seems to work all right.
Here are some minor optimisations:

- Do the fast all-ASCII test (bytes == chars) before iterating through the bytes to check for non-ASCII chars.
- Faster check for non-ASCII non-raw bytes (no need for the complex code in string_char_advance).

It is tempting to vectorise the all-ASCII loop. Maybe another day...

The patch also adds some more test cases for completeness.
