They say JSON is not for binary and won't change. With a backslash (oops reverse solidus) you could send binary data - eg an image. { myimage: "\01\02\03" } of course, not efficient. You could base64-encode it and put that in a string. I think some syntax for binary would be useful - eg { myimage: 0x010203 }
Interesting. It says they're the same thing, but then the two characters listed on the page (the regular backslash and the Unicode variant) are rendered noticeably differently.
Look at the HTML. The "unicode variant" is rendered differently because the code tells the browser to render it differently, not because it's a different character.
