Microsoft's Kartika and other Malayalam Unicode compliant fonts(Anjali, Rachana) behave differently for following NA, RRA combinations. This introduces error in the texts being produced currently.

Current behavior of the fonts[]
Karthika produces from <NA, VIRAMA, ZWJ, RRA>. Anjali and Rachana produces from both <NA, VIRAMA, ZWJ, RRA> and <NA, VIRAMA, RRA>. None of them produce from <NA, VIRAMA, ZWJ, ZWJ, VIRAMA, RRA>.
