I haven't read the MAC spec recently enough, did you already deal with the character set issue (if there was one) comparable to the ones in the Bearer spec?

I am +1 on the -body_hash +ext change.

Subject: [OAUTH-WG] MAC: body-hash
 

I want to reaffirm our previous consensus to drop the body-hash parameter and leave the ext parameter. Body-hash as currently specified is going to cause significant interop issues due to character (and other) encoding issues. Providers who desire to MAC the body can define their own ext use case.
 
Let me know if you have an objection to this change.
