Re: Convert the hexadecimal character code to the corresponding Unicode value.

[Eduardo Ochs <eduardoochs@gmail.com>]

Hi Hongyi,

does this help?

                  (string-to-number "1D4E0" 16)
  (char-to-string (string-to-number "1D4E0" 16))
          (string (string-to-number "1D4E0" 16))
     (format "%c" (string-to-number "1D4E0" 16))
          (insert (string-to-number "1D4E0" 16))

The entry for 1D4E0 in UnicodeData.txt is:

  1D4E0;MATHEMATICAL BOLD SCRIPT CAPITAL Q;Lu;0;L;<font> 0051;;;;N;;;;;

I have some hacks to display the characters around a certain
entry in UnicodeData.txt here,

  http://angg.twu.net/.emacs.html#find-echars-around
  (find-wgeta-elisp "http://angg.twu.net/.emacs" "find-echars-around")

but the code is ugly - I wrote it in a hurry ages ago and never
cleaned the code up...

  Cheers,
    Eduardo Ochs
