Short answer: you can't, it's too hard.
You'd have to write something that understood all possible encodings.
And you'd be breaking dkim signing.

Similar problem, though more tractable as these are almost certainly
UTF-8, so you only have one suite of encoding rules to deal with.
Indeed, there might be enough support in the RE library that ${sg }
sits on to spot UTF-8 characters as single items.
Or, if they're always in the same place, use surrounding info to
know when they're there and just edit those bytes positions out.
