For example:
if char is cyrillic and previouschar is arabic:
\fontspec{SomeCyrillicFont}
end
And also:
http://wiki.luatex.org/index.php/Token_filter
I'm thinking mainly in short chunks of texts, like a proper noun
inside an Arabic o Devanagari text.
I think pre_linebreak_filte is too late and process_input_buffer
is too soon, but I may be wrong. Or perhaps the best solution is
not based on a callback at all.
