Javascript code only "sees" strings as a sequence of Unicode
characters, the internal representation of those characters in memory
(UTF-8 or otherwise) is hidden and inaccessible. U+0000 through to
U+00FF are all valid Unicode characters, so it's certainly possible to
use a Javascript string to store a sequence of arbitrary octets, but
they will be taking up more space in memory than just that number of
bytes.
