The fact the UTF-8 was first "implemented" on Plan 9 has nothing

Not true. The ability to adapt the system quickly in response to a
changing standards situation made a critical difference in having
UTF-8 rather than a weaker proposal accepted by X/Open

There are many things here that feel wrong or at least inelegant, starting

it, sometimes you use a substitute. It's more efficient in both time and
