Character 208 acts strangs in console, when moving mouse

[Willem Hendriks]

When i display character 208 in my console and move my mouse, i see the strangest things. 
FreeBSD 6.2-RELEASE-p8, with default screenmap and console settings.

wget and cat that file in a console to see the effect.

I tried it on my laptop and desktop PC with same kernel. Anyone else experience this problem/effect? I think it should be a pi character upside down, mostly used to draw tables in combination with other characters...
