Not quite by Irving Berlin

There's no ASCII but US-ASCII, the only ASCII I know,
Everything about it is U.S.-based,
Everything about it's seven-bit.
You do that X3.4 wheeler-dealing
When you're feeling retro-fit.

There's no ASCII but US-ASCII, it's Unicode's first half-row,
Though it is a turkey that we know must die,
While systems chop off the bits that are high,
It is the only charset that will always fly,
ASCII, backward we go!
ASCII, on with the show!
