There is no such thing as a 'regular keyboard'. Each country has its own national version, and that you happen to have these symbols, doesn't mean that others have them. (Have you ever been in Taiwan?) I do have í on my PC, but not on my laptop.
I think the only place I'd allow characters outside the ASCII standard, such as letters with diacritics, would be as atoms in connection with the custom moves that we've discussed before. Even then, I'd limit it to the capitals in the ANSI/Windows-1252 set (À to ß, skipping × but possibly also including Š, Œ, Ž, and Ÿ). I say this in spite of the fact that I can think of specific uses for several other characters on the lower half of the Windows-1252 table, as modifiers.
Examples of what I personally might assign to those letters include Ø as a null move, Þ for a Rose, Ñ for Quintessence, and Ê for Edgehog. (Maybe even Ä as Aanca, as a Griffin/Manticore compound that could be broken down into orthogonal or diagonal.) But, again, I'd build them as "custom moves" (though I'd also make the code easily available to others).
