That might work well if the goal is to find a compact encoding to 7-bit
code units, then express 8 such code units in 7 bytes. It would
certainly be more economical than UTF-7-over-7, which is fine for ASCII
and awful for anything else.

I don't usually think of Punycode as an ideal general-purpose
compression encoding, especially with lines of arbitrary length or
consisting primarily of non-ASCII content (Cristian's example), but it's
certainly worth experimenting. One advantage might be that encoders and
decoders for Punycode already exist, probably in greater numbers than
for SCSU.
