W3C indicates that Character References #128 to #159 are forbidden[2]. The Netscape de-facto "standard" appears to correspond with the Wintel ANSI standard over this range, which is swell for Wintel users and Hellish for Mac users using other than the Big Two browsers. Indeed, looking at the chart, it appears that Mac Roman Standard is the "odd man out". This is likely due to Apple needing a standard years before Wintel needed one, and SGML References, and ANSI Windows coming to exist around the same time. (More information on this topic is available at Why doesn't the Macintosh use Latin-1?)

Whatever the case, here's what your browser does:

[2] I've lost my precise sources which specifically used the word "forbidden" (or close). A look at The HTML Coded Character Set from HTML 2.0 or later will clearly show positions 128 to 159 as "unused".
