The benefits of everything being a buffer in Emacs
The Unicode has a Unihan_Readings.txt file that can be transformed into a readings-table for Emacs to help you accelerate your learning the character definition and key sequence for input method.  To help your eyesight you can configure Emacs to enlarge the East Asia fonts.  What I don&#x27;t know how is to append to the &quot;chinese-ctlaub&quot; input method missing key sequence for input method.<p>For example, 雈, code point #x96c8, the chinese-ctlaub input sequence is missing.  I&#x27;d like to update chinese-ctlaub with the reading &quot;woon4&quot;.<p>See <a href="https:&#x2F;&#x2F;humanum.arts.cuhk.edu.hk&#x2F;Lexis&#x2F;lexi-mf&#x2F;search.php?word=雈" rel="nofollow">https:&#x2F;&#x2F;humanum.arts.cuhk.edu.hk&#x2F;Lexis&#x2F;lexi-mf&#x2F;search.php?wo...</a><p>Here is the emacs lisp configuration.<p><pre><code>     1
