Detailed Description

The “binary” pseudo-charset.

binary is special in that it's not really a character set; conversions from another charset to binary means “erase the charset information” and conversions from binary to another charset means “interpret these bytes as the destination charset”. In other words, in no event are the bytes changed; you can think of binary as the charset equivalent of void * that you can cast through. Needless to say, this also means that using it can be rather dangerous.
