Yes.  Parhaps the string body can be shared.

|a) What would I use instead of ?A, then?

"A"

|b) What issues are there with keeping the ?A notation and instead allowing
|?[utf-8 character here] notation?

?[utf-8 character here] still works.

|c) How can I write my code so that it is compatible both with Ruby 1.6 and
|with the Ruby M17N framework?

Use ?A.  It will not be removed, just declared obsoleted.

|Can you elaborate on this?

No, we can't.  Since I don't have concrete idea yet.
