Works great with the typo's fixed. Is there a way to do this only for koron and 
sori and render the
normal accidentals as usual?

If I do the same for KeySignature

\override KeySignature #'text = #(lambda (grob)
          (cdr (assoc 
 (ly:grob-property grob 'alteration)
                   persianStrings)))

gives me an error. It's been almost 20 years since I've used Scheme and I don't 
remember
enough to be able to guess what the problem is...

Thanks a lot!
