Built-in post processors

Post processors run after interpolation when their keyword is listed in the postProcess argument (postProcess = "sprintf" or postProcess = new[] { "interval", "pseudo" }).

Post processor	Keyword	Description
SprintfPostProcessor	sprintf	Replaces %s, %d, ... placeholders in order with the values of the sprintf array
IntervalPostProcessor	interval	Picks an interval like (1){one};(2-7){a few};(8-inf){a lot}; by count
PseudoLocalizationPostProcessor	pseudo	Replaces letters with accented look-alikes to find hard-coded or truncated texts

PseudoLocalizationOptions configures the pseudo localization: LanguagesToPseudo limits it to some languages, LetterMultiplier and RepeatedLetters lengthen vowels to simulate longer translations, Letters maps the characters and WrapStrings adds brackets around the text.
