It means that PHP doesn't care if a string contains NULLs, so we are  
just discarding the ~ when it is part of the literal8 construction  
(since a NULL is treated as a single-byte character for PHP string  
processing).

RFC 6855 support is irrelevant here - literal8 is defined by BINARY so  
this can be tested on a server that supports BINARY.  Thus, if you  
have a fix Jan you don't need access to a UTF-8 server to properly test.
