I think printing binaries in a string-like manner is
very handy. Please do introduce it, OTP.

Richard O'Keefe's postings here on the topic of modern
character sets have made me realize this is not a
trivial issue, alas.

Yes.

My lex.erl in jungerl can already do lexing over
binaries (it works for the examples I have tried, at
least). Only 8-bit characters though. I haven't
measured how this compares to lexing over lists. The
"lex driver" can probably be optimized a bit in both
cases.
