Разобрать текст VT100 с цветами (для регулярных выражений)

Question

Я использую Apache TelnetClient для подключения через telnet и хочу изменить кодировку на обычный текст.

Однако при попытке обработать ответы VT100 String ответ приходит с цветом. Как удалить цветовые кодировки, чтобы получить простой текст?

Я заканчиваю с фрагментами вроде (только для иллюстрации):

You say: confusing the hell out of bob.

Проблема в том, что цветовые коды CSI приходят вместе для поездки. Как я могу конвертировать String кодировка из VT100 в обычный текст?

Пример кода Java для иллюстрации:

/***
 * This is an example of a trivial use of the TelnetClient class.
 * It connects to the weather server at the University of Michigan,
 * um-weather.sprl.umich.edu port 3000, and allows the user to interact
 * with the server via standard input.  You could use this example to
 * connect to any telnet server, but it is obviously not general purpose
 * because it reads from standard input a line at a time, making it
 * inconvenient for use with a remote interactive shell.  The TelnetClient
 * class used by itself is mostly intended for automating access to telnet
 * resources rather than interactive use.

Тем не менее, в зависимости от сервера, к которому вы подключаетесь, ответ не будет простым текстом - приведенный выше код только для иллюстрации, чтобы показать использование для ApacheTelnet,

Альтернативно, можно ли установить Apache TelnetClient экземпляр, чтобы принимать только простой текст через TERMINAL_TYPE поле? Тем не менее, это поле является окончательным...

Сложно запустить регулярное выражение для цветного текста VT100 - как вы игнорируете цвета? Или работать только с простой текстовой строкой?
