Agreed, but the example was from Windows 2000. It should at least be current
through Unicode 2.1.

I would question that. Understandable, yes, but not really correct.

True. I have also heard "roman" used to mean the opposite of italic.

Here is my list. Remember that I am expecting information supplied with
Windows 2000 to be current through Unicode 2.1.

This implies that development was finished in 1991, and only new characters
are added. In fact, lots of new development to Unicode has taken place since
then (just look at all the TR's). This might be splitting hairs.

Even "16 bits" would be better than "two bytes" here, but again this is

Hey, they got something right!

I thought "Roman" was simply an alternate word for "Latin," but Jorg is
correct. This is also an error.

The count was correct once, but that was 10 years ago.

"Combinations"? You mean of two bytes?
Well, that's about enough. I am not a habitual Microsoft basher, but
somebody in their Help department really needs to update the information
distributed with their OS. Tex is right that we are bound to see a certain
amount of misinformation, but it is our duty to help correct it.
