It's not *wrong*. It's not a matter of the Right Thing and the Wrong Thing.
For some purposes, code units (8 or 16 or 32 bits) are the Right Thing;
for some purposes, codepoints are; for some purposes, higher-level units
are. It's about appropriate choices.
And if Unicode is complicated (and it is), it's because it's embedded in
a complicated world.

Most languages are dramatically underdescribed, and at least one is
dramatically overdescribed. Still other languages are simultaneously
overdescribed and underdescribed. Welsh pertains to the third category.
