I'm inclined to say no. Multibyte doesn't magically solve any
problems you might have with multibyte encoded strings. It solves
problems with encoded strings in most Rails methods that handle
string somehow, like view helpers.

Have you checked what the actual encoding of the strings is before
you assign to the string? One good test to is too check if they're
utf-8 by calling String#is_utf8?.

Most data processing pipelines still aren't utf-8 by default. You
have to make sure that everything is doing the utf-8 dance. So make
sure the page where the request is coming from was served
with ;charset=utf-8 in the content-type. You might even want to
specify the content-type with a meta tag.
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
If you're getting Ajax request from a page beyond your control, you
might be out of luck because it's hard to find out what encoding your
getting the string in. If you know what encoding they're sending you
can fix the encoding with iconv.

If it doesn't work in the rails-1.2 pre-release branch, it's probably
not going to change for the release unless it's a major bug. It is
very possible to install ActiveSupport::Multibyte in older versions
of Rails. You only get the ActiveSupport::Multibyte namespace with
all the operations, not all the code fixes currently in edge. You can
find more information about this on: https://fngtps.com/projects/
