Input Unicode by It's Hex Value in Emacs

(last-edit-by: lgfang 10/21/2006 19:29:43>)

To type in unicode chars by their hex value. You can as following:

1. M-x set-input-method <ret> ucs <ret>
2. Key in u+hex to enter a char. For example, unicode of alpha(α) is 03b1 so you would key in 'u03b1' to get the char.

Tip 1:

I experienced errors entering some chars when I set set-keyboard-coding-system as euc-cn. After I change it to nil, errors fixed.

Tip 2:

To tell Emacs a file was encoded with utf-8 you can add

       -*- coding:utf-8 -*-
       

in the first line of it if Emacs can't detect that by itself.

Tip 3:

To see the unicode of a char, move point on it and then "C-x ="
