Not that the national charaters are exactly usefull in console due to the OS's english nature - BUT by god - You need to have the keyboard configured to enter a simple # char by pressing the corresponding key with that symbol.
Else You get all kinds of other chars (like a silly pound sign etc.).
go sudo (or call for him) - the SUPERUSER and write:
dpkg-reconfigure keyboard-configuration
wait a moment and select keyboard type (default marked) and Your language (indo zulu or whatever..)
at end reboot (by writing that or kill the fruit by unpowering)
note: wonder why not anyone else has asked for this - i tried search. Maybe only english ppl get a Pi and therefore
