Currently creating unibyte strings with the C module API is rather
convoluted: one has to create a list with the individual bytes and then
call `unibyte-string', requiring lots of memory allocations. Given that
creating a unibyte string is more fundamental than creating a multibyte
string, I propose adding functions to create and extract unibyte strings
that exactly mirror the existing support for multibyte strings.

Can you explain why you need to create unibyte strings, or describe a
use case where this would be required?

I don't have a concrete use case per se, but the API feels incomplete
without this functionality, especially given that creation of multibyte
strings is supported and uses unibyte strings under the hood.
I'll let +Daniel Colascione <dancol@dancol.org> chime in for his opinion.

Unibyte strings are very rarely used in Emacs core, and for a good
reason. So I think we'd really want to see real-life use cases before
we decide to support them in modules.

Is there any use-case here? Otherwise, it sounds to me like Eli thinks
that this should be closed as wontfix? Thanks.

More information was requested, but none was given within 7 weeks, so
I'm closing this bug.
