Sun's hardware console doesn't behave the same as xterm or vt100.
I'd expect $TERM to be either "sun" or "sun-color" for that.

(A while back, Sun got in the habit of setting $TERM for their installer,
so that it would't run properly on the console, apparently assuming that
it was run on an attached serial terminal).

For what it's worth, the terminal description for "sun" does not
mention line-drawing.  (It's been quite a while since I looked at
Sun's documentation, but I probably wouldn't have overlooked that).

Also, it didn't do UTF-8.

In Unicode, ACS_HLINE would be U+2500, and the character you're showing
is (in ISO-8859-1) 226, or octal 342.

The UTF-8 for U+2500 is


So... it seems you're displaying UTF-8 on a device that supports ISO-8859-1.
