Arrows would fire very poorly as there is no traction for the fletchings and hence no stability. They'd still go on through space, however, just not with the arrowhead in the direction of travel all the time.
The fletchlings are there to counteract the air resistance on the tip. And in space there is no air resistance. If you shoot it straight, it will fly straight.
The fletchings are there in order to create drag to counteract the back's propensity to fly in front of the tip. Try to shoot an arrow without fletchings straight; it's suddenly lost its usefulness as a weapon.
And the back has this tendency because of the higher amount of drag on the tip. Since there is no drag in space, this no longer applies.
I know it becomes less usefull inside our atmosphere, but that's not what we're discussing.
Theoretically, if there is a straight force behind the arrow, the arrow will fly straight.
I doubt, however, that there is a shooter who can shoot an arrow without the slightest amount of spin. This small force, in the atmosphere, would be corrected by the fletchlings. In space however, it would not.
