Assuming that you're aiming for the nipple slot and get no stretch you can use spokes that are at most 2.5mm too long. You get about .5mm of stretch on a 2.0/1.8 spoke which leaves 2mm.
If you were aiming for the top of the nipple 1mm too long can bottom.
Other spokes and nipples are similar.
If it is a DT Swiss brass 12mm nipple, their 9.5mm threaded spokes will stop about .50 - .75mm past the top.
DT Swiss alloy 12mm nipples tend to be a little more liberal and will often allow the same spoke to protrude as much as 2.0mm past the top.
Not sure why they do this - I've never asked...
