OK, thanks. By the way, I find that either I've to use AMS as document
type, or add "\usepackage{amsfonts}" in preamble for \mathbb to work. I'm
still using version 1.0.4, maybe in latest version I don't have to do this?

Actually, the R displayed is a "hollow R" but not the R used to
represent the set of all real numbers. But it's better than nothing :)

This is of course an ideal solution, but I'm afraid this would demand
too much effort from developpers. They're programmers, not designers :(

OT: there's a TrueType Cyberstream Unicode font file, free of charge,
available. If you're using Linux with a TT font server, you could use this
font. However, this font was provided years ago, so maybe something are
missing. "Euro" is certainly missing. But personally, I prefer Microsoft's
approach in Unicode. MS provides separated fonts for every language family
and all of them constitute Unicode, instead of a single font file containing
everything. The reason is that while Times Roman or Helvetica/Arial style is
meaningful for Latin letters (or even Greek and Cyrillic), they are almost
meaningless for other language families. It's thus quite silly to provide a
"Times Roman Unicode" font file.

Yup, except for matrix, for example :-)

Are you sure it's "because" but not "therefore"? They're very
different. Please note that I'm talking about the meaning, not the exact
latex syntax because I don't know.

I learnt latex from written notes that my professor gave me, and
sometimes from Internet if I find any. I don't have any reference book. So
please tell me what they are.
