//TODO - improvements
//- optimize speed - don't use regexes, extract the last word with substring()
//- optimize size - declare correct spellings like this w('Śiva,Śakti,...');
// - automatically deduce the non-diacritics correspondent
//- matching to be case insensitive, preserve case for the first letter
//- auto build dictionary in a webpage
// - detect all diacritic words from the textarea, add to dictionary
