First I go to the Language Support window. Either search (press Super/Windows, then type) for

"Language Support" and go there directly, or search for "Region & Language", go there, then click

"Manage Installed Languages".

There I click Install / Remove Languages ..., check the Chinese I want, then click Apply.

Then I add the packages for the input methods I want, either using the command line (apt install)

or the Ubuntu Software application:

Chinese Quick: ibus-table-quick-classic

Chinese Pinyin: ibus-libpinyin

Chinese (Cantonese) Jyutping: ibus-table-jyutping

Bonus input method:

Unicode emoji: ibus-typing-booster

Now for each user that wants an input method, I search for and go to Region & Language. At the

bottom of the Input Sources section I click the plus button. The different input methods are found

by clicking down into different sublists. Click the right choice, then Add:

Chinese Quick: Chinese -> Chinese (QuickClassic)

Chinese Pinyin: ⋮ -> Other -> Chinese (Intelligent Pinyin)

Chinese (Cantonese) Jyutping: Chinese -> Chinese (Jyutping)

Unicode emoji: ⋮ -> Other -> Other (Typing Booster)

EurKEY: English (United States) -> EurKEY (US based layout with European letters)

The EurKEY layout is part of the standard English language support in Ubuntu.

Finally, to enable unicode color emoji as completion suggestions, switch to the Typing Booster mode

by pressing Super/Windows+Space repeatedly until you see the rocket in your notification area. Click

the rocket -> Unicode symbols and emoji predictions -> On.

I owe you a followup episode once I figure out how to make this work for Guix applications running

inside Ubuntu.

References for your further study:

IBus is an input method protocol for the

GNU/Linux desktop. Other protocols supported are XIM,

SCIM,

fcitx and uim. You

have to choose one of these to use for all your input methods, but the most common input methods

exist at least for IBus and the first three of the rest, so this is not as much a limitation as

it sounds like.

Quick is a simplification of the

Cangjie input method. Cangjie assigns

radicals, character components, to 24 keys on the alphabetic keyboard, and you combine these into

a character. In Quick you combine two and then choose a completion from a list.

Pinyin is a romanization, a Latin alphabetic spelling,

for Standard Chinese (Mandarin).

Jyutping is one of

many

romanizations

for

Cantonese.
