That's not a reliable sign that a function returns unibyte strings.
Most Emacs APIs that decode strings don't signal errors if they
encounter invalid sequences; instead, they decode those into raw
bytes. The design principle is to support raw bytes in strings and
let the application deal with them if they are not expected.
