Subject: Fix Unicode name mangling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`{` and `}` aren’t valid characters on ARM.

This also fixes a small bug where `)` (**r**ight **p**arenthesis) and `*`
(**r**aw **p**ointer) would both mangle to `$RP$`, making `)` show up as `*` in
backtraces.
