Other than the fact that two Microsoft people have already said they
aren't changing the definition of CP1252, it seems a little odd to have
a mixture of 27 graphical characters with five of the least-used C1
controls. In a real 1252 environment these five characters (81, 8D, 8F,
90, 9D) will not occur, as mentioned before, and in a normal Web-based
8859-1 environment (neither embedding 8859-1 within 2022 nor using an
ISO 6429 terminal) the chances are equally remote.

I'm still trying to wrap my head around this:

implying that a Microsoft standard isn't a standard.

But in any event, also as mentioned before, this entire discussion is
moot for HTML5, since WHATWG knows better than Microsoft or Unicode how
CP1252 is really defined:
