% Thaa sukun rules, mapped to <TS>

% preceeded by other vowels, behaves like <AS>
% must cascade those rules after

% alif and shaviyani sukun rules, mapped to <AS>

% nasalise if followed by haa, alif(vowel)

% Next consonant will geminate
% Still needs some work

% alif sukun is supposed to drop a coda /k/ at _ # sometimes
% at boundary which we ignore fallback to a stop instead
