Kubuntu 20.04 solves the problem of garbled Chinese characters displayed on the terminal

Phenomenon

After installing kubuntu 20.04 system and Sogou input method, I found that neither kconsole nor deepin-terminal can correctly input and display Chinese

solve

The factory configuration of kubuntu 20.04 does not use the Chinese character set, resulting in garbled Chinese characters

$ locale

LC_CTYPE="C"
LC_NUMERIC=zh_CN.UTF-8
LC_TIME=zh_CN.UTF-8
LC_COLLATE="C"
LC_MONETARY=zh_CN.UTF-8

LC_ADDRESS=zh_CN.UTF-8
LC_TELEPHONE=zh_CN.UTF-8
LC_MEASUREMENT=zh_CN.UTF-8
LC_IDENTIFICATION=zh_CN.UTF-8
LC_ALL=

Set the correct Chinese environment:

1. Pure Chinese system

Set environment variables LC_ALL=zh_CN.UTF-8, other environment variables starting with LC are set tozh_CN.UTF-8

2. Chinese can be input, but system information such as menus and titles are displayed in English

Only need to set the character set of the systemLC_CTYPE=zh_CN.UTF-8

You only need ~/.profileto ~/.bashrcadd in or export LC_CTYPE="zh_CN.utf8", and you can enter Chinese normally after restarting

Of course, the following can also be set individually:

• number formatLC_NUMERIC
• time display formatLC_TIME
• Currency UnitLC_MONETARY
• Unit of measureLC_MEASUREMENT

But these can be found in the system settings interface

In addition, similar LANGto LC_ALLthe function , set the default value of other LC beginning variables, but the priority is lower and can be LC_ALLoverwritten

Priority: LC_ALL> LC_*>LANG

LANG - Specifies the default locale for all unset locale variables
LANGUAGE - Most programs use this for the language of its interface
