        The appearance of the syambol 'R' to denote real numbers is not unique.
        It varies from book to book. Most mathematics books would have the
        shape you've described, but some other books have the sahpe which is
        neither like an R with an extra line on the left nor the R given
        in the symbol font set at the 0194 position. It seems to me that,
        this particular shape or R at 0194 is a creation of Microsoft.

        Two points to note here.

   1.   The previous claim was that 'there is no such R character in the
        symbol font set that can be used to represent real numbers.' At
        that point I suggested to try the outlined prescription before
        making such a blunt comment. However, now the claim is this R is
        not the one used most often (!).
        I have used that R from the symbol font in my thesis to represent
        real number and I passed. I never thought the committee didn't
        know how a 'Re' symbol looks like. Probably I went lucky, huh?

   2.   Character 0193 and 0194 in the symbol font set can be used to
        represent imaginary (I) and real (R) numbers. Actually there are
        few other symbols around this region of the font that are used
        in the set theory. What one has to be careful about is the
        character alt+194 and the character alt+0194 are NOT the same!
        One must press the zero and then the 3 digit code to get the
        correct symbol.

        I must point out that I don't have enough idle time to spend for
        this pointless matter. Your constructive comments are welcome but
        I'll probably have to refrain myself from reciprocating unless
        it is something worth. I yelled 'Shut up' to my friend, but now
        have to take her lunch. I wish people practised what they'd like
        to preach (think!).
