Perhaps at the time when this CTLau-b5.html was composed that was the
extent of what was known or the authors hadn't encountered a use for
it to be included.  Those two codepoints are documented at page 185 of
U4E00.pdf .  They represent two forms of citrus fruit.

Looking at the below for #x6a58

  - https://humanum.arts.cuhk.edu.hk/Lexis/lexi-mf/search.php?word=%E6%A9%98

The left margin section, at the bottom, has a drop down menu and the
CTLau phonology is obtained by selecting the bottom option.

There the phonological reading for #x6a58 is given by gat and gwat.

Looking at the CTLau-b input sequence for \foh

  - https://humanum.arts.cuhk.edu.hk/Lexis/lexi-mf/search.php?word=%E7%85%92

the humanum gives the reading wai, is there any memory for some
CTLau-b input sequences having the backslash prefix?  The sounding foh
refers to the fire character indexical is my guess which might have
been a mnemonic for the authors of CTLau-b5.html .

I would like to use the phonological readings gvien at the humanum website.

I've tried to contact them but got no reply.  It would be neat if they
update the CTLau-b5.html file.

That page is a random page in the Shuowen dictionary with two
codepoints for orange and tangerine citrus fruit which I thought would
be in common use enough to be covered by the CTLaub input method.  One
of them is not available. I am hoping for an accommodation to allow
updating the CTLaub input method.  Perhaps the user can compose a
CTLau-b5-extend.html for use.

I was likening the input method function to spellchecking.  The input
method function does not accommodate updates but the spellchecker will
let you add new word spellings.
