arraysEqual(dynamic ar1, dynamic ar2) → dynamic
getSubstFormat(dynamic lookupTable, dynamic format, dynamic defaultSubtable) → dynamic
prototype() → dynamic
Substitution() → dynamic: Add a substitution to a feature for a given script and language. @param {string} feature - 4-letter feature name @param {Object} sub - the substitution to add (an object like { sub: id or ids, by: id or ids }) @param {string} script='DFLT' @param {string} language='dflt'
