Hi,

I only followed that discussion loosely until David submitted a 'spanish
charmap' a few days ago. Looking at our available charmaps, I see no
reason why not to map ñ or Ñ to the 'n with above dash' character.

The datasheet for HD44780U from Hitachi shows this character. I have
checked with all displays available to me, and they show that character,
even if the use different controllers.

Beside that, to help testing character sets, I added a 'none' charmap
(patch attached), which does not translate anything. Use this in
combination with the charset demo from the testmenu (./configure
--enable-testmenus). You need a keypad to make use of it!

Additionally I found a typo in the euro_charmap and the charset demo
code which I will fix soon.

Regards,
Markus
