I'm not sure it is.  An unwise design choice by 4.4BSD, yes.

U+0081 as 0x81 is ‘is a character representable as an unsigned char’ for
it's a character, U+0081, and unsigned char holds [0, 0x100) so it
suffers no loss of representation as an unsigned char.

Though following that argument, every implementation should be doing it.
