The ANSI-BBS Translator interprets a subset of X3.64 (also known as ECMA-48) escape sequences.
The ANSI-BBS translator is marked as message-safe and user-safe when used under its default settings. This means it is considered safe to use the translator when displaying email or text written by the user. The translator filters out unrecognized escape sequences, including those use to manipulate keyboard mappings. If you disable the filtering option, the translator is no longer considered safe. This is because some ANSI sequences are used to control video modes and keyboard mapping. It may not be safe to send these sequences to terminals that blindly execute them.
