It is.

The "u" in "c-addr u" as well as the count byte in counted strings
specifies the number of bytes, not Unicode code points (xchars) nor
Unicode characters. And the character count is not really interesting
for rendering. This is a simplified view, but it's the relevant one
on byte-addressed machines when using UTF-8 encoding.
