Comment(by dev@…):

 That's not true.


 {{{
 #!/usr/bin/env ruby
 # encoding: UTF-8
 s = "a".force_encoding("BINARY")
 puts s.encoding
 puts [s, s].join.encoding
 s = "\xA4\x01".force_encoding("BINARY")
 puts s.encoding
 puts [s, s].join.encoding
 }}}

 Gives me

 {{{
 ASCII-8BIT
 ASCII-8BIT
 ASCII-8BIT
 ASCII-8BIT
 }}}
