как да конвертирате от разширен ASCII в EBCDIC и обратно, когато кодът на страницата е неизвестен

Имам два масива, използвани за конвертиране от ASCII в EBCDIC и обратно. Контекстът е: има MyMainframeApp, работещ в UNIX и изпраща/получава само файлове в EBCDIC. Такива файлове трябва да бъдат прочетени от MyWebApp във формат ASCII, обработени и върнати в EBCDIC. Следващите два масива отговарят перфектно на преобразуването. Проблемът е, че сега трябва да поддържам Extended ASCII (вижте последния масив, който получих от интернет), така че искам да присъединя EXTENDED_Array към ASCII []. Какви биха били еквивалентните кодове в EBCDIC? Приложението трябва да работи под Windows 2012/JDK 6 и Unix/JDK 6 еднакво. Има ли безопасен начин да направя това, ако не знам кода на страницата? Забележка: Не питам как да преобразувам от ASCII в EBCDIC (в този форум има добри отговори на този въпрос). Първо, бих искал да поставя на спот светлина "EXTENDED", след което питам какъв е еквивалентният масив за Extended ASCII по-долу и дали има безопасен начин да работя върху него, когато не знам за кода на страницата.
