I hadn't, and as long as I control the data I'm displaying, I won't have to.

Blame those systems, not me.

What you suggest is surrendering to the state of affairs, which we collectively self-inflicted.

When I have to deal with normalization issues and have to interface with external systems, I can still go looking for a library if I don't feel like implementing it on my own (which is likely).

But unless I need to do normalization, I'm way worse off with a complicated library than with just doing memcpy() or using a simple decode_codepoint() routine.
