As far as I can tell from the documentation, the semicolon is required as part of the syntax for entity reference. So a non-breaking space must be not  . However, it looks like Safari is the only browser that DOESN’T render entities without a semicolon. Does anyone know why? Both Safari and Chrome use webkit, yet Chrome renders regardless of the semicolon.

It’s the input part of the principle of Generous on Input, strict on output. Different browsers choose different measures of “generous”.
