\0314\0202 = 11001100 10000010 Which breaks up to 110 01100 (first byte of 2-byte sequence) 10 000010 (nth sequence byte) Which becomes 01100000010 = U+0302 COMBINING CIRCUMFLEX ACCENT (^) With the WIP combining character patch I sent to the list some time ago now it shows as "x̂yz" (but does other weird things when entered into a non-empty terminal). gnome-terminal behaves equally weird with moving the cursor some amount of lines up, not printing hello or the hat. -- Joakim
