Good question, I do not have the answer but see three posibilties ;-)
1. Do nothing - Does not solve the problem.
2. Name the street as " "(Just a space) - I do not know if the system accept this, and it is not really correct.
3. Name the street and other similar streets in the village "Tjåmotis" - This is probably the solution that is least wrong ;-) and closest to what the adresses for people living there look like.
