Miglioramento nella gestione delle sostituzioni inline per le traduzioni, con aggiunta di alcune opzioni integrate per modificare l'output (tutto maiuscolo o tutto minuscolo). Aggiunta della libreria danielstjules/stringy per migliorare la gestione delle stringhe con supporto completo alla codifica UTF-8.
