Alt-Gr+~+n does not work

[Moltke]

Hello Moltke,
Thanks for you answer. The layout of my keyboard is german. Beside the "l" is the letter "ö" located.

Hmmm...well, maybe you should try changing your keyboard layout when writing in Spanish? Or, get/use a virtual keyboard with a Spanish layout. Sorry, but since I don't have and never have had this problem cause my keyboard's Spanish this is all I can think of.

EDIT: On a second thought, it might pay taking a look at keyboard settings and changing the keyboard type for something that supports "AltGr+n" so instead of "generic keyboard" try something like "dead keys" or whatever that works for you...just an idea.
