Since input was converted to &str anyway there is no reason not to require it upfront. This also makes that API has more sense, since now it is obvious that "a slice of bytes that you want to be written out to somewhere" is an UTF-8 encoded string.
Expected data in tests is now a string slice, not a byte slice. Changed concat! macro in favour of r#"" strings.
Cleaned up say. Removed unnecessary intermediate Vecs. Added some comments.

I changed
inputto be&strinstead of&[u8]since it is more clear now what it does and the only thing that was done with it was converting it to&stranyway.Also cleaned up tests and "drawing" part of
sayfunction.
