Ah right ! Thanks. Narrow is Na.  

So a refined algorithm would be to actually do the summation in each grapheme cluster as I initially wanted to do with the mapping (F, W -> 2), (Na, H -> 1) (N -> 0) and if I get a 0 fallback on 1 or maybe try to make an educated guess according to the script/block.

Best,
