How do you represent bencoded strings that contain a tag to avoid ambiguity with the tags introduced by not utf-8 bencoded strings?

Maybe we can always include some tags. For byte sequences containing valid UTF-8:

"<utf8>spam</utf8>"

And not UTF-8 sequences:

"<bytes>fffe</bytes>"

The encoded value 6:<utf8> would be "<utf8><utf8></utf8>".

Maybe we can event simplify the metadata using just a prefix instead of a html-style tag:

"utf8:spam"

And not UTF-8 sequences:

"bytes:fffe"

What do you think @da2ce7 @mario-nt ? It's just the first idea I came up with.
