=begin
Does Ruby allow 8 bit characters (127-255) in a US-ASCII encoded string, or not?

   "\u{80}".encode("US-ASCII")      #=> Encoding::UndefinedConversionError
   0x80.chr("US-ASCII")             #=> "\x80" (US-ASCII encoding)
   "".encode("US-ASCII") << 128     #=> "\x80" (US-ASCII encoding)
   "".encode("US-ASCII") << 128.chr #=> "\x80" (ASCII-8BIT encoding)
=end
