All these lonely accents, where do they all come from?

Text doesn't appear out of thin air, Keith.

Please explain exactly where you think unnormalized UTF-8 text enters
the world's computer systems.

Then explain why you think normalization should be put into every
program that _handles_ text, instead of the much smaller set of programs
(notably, keyboard interfaces) that _produce_ text.
