Question

$ locale
LANG=en_US
LC_CTYPE="en_US"
LC_NUMERIC="en_US"
LC_TIME="en_US"
LC_COLLATE="en_US"
LC_MONETARY="en_US"
LC_MESSAGES="en_US"
LC_PAPER="en_US"
LC_NAME="en_US"
LC_ADDRESS="en_US"
LC_TELEPHONE="en_US"
LC_MEASUREMENT="en_US"
LC_IDENTIFICATION="en_US"
LC_ALL=en_US

一切都很好：

$ man du

DU(1)                            User Commands                            DU(1)

NAME
       du - estimate file space usage

SYNOPSIS
       du [OPTION]... [FILE]...

DESCRIPTION
       Summarize disk usage of each FILE, recursively for directories.

       Mandatory arguments to long options are mandatory for short options too.

       -a, --all
              write counts for all files, not just directories

       --apparent-size
              print apparent sizes, rather than disk usage; although the appar-
              ent  size  is  usually  smaller, it may be larger due to holes in
              ('sparse') files, internal fragmentation,  indirect  blocks,  and
              the like

       -B, --block-size=SIZE use SIZE-byte blocks

当我更改LC_ALL时：

$ LC_ALL=en_US.utf8
$ locale
LANG=en_US
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=en_US.utf8

现在变得糟糕了：

$ man du

DU(1)                            User Commands                            DU(1)

NAME
       du - estimate file space usage

SYNOPSIS
       du [OPTION]... [FILE]...

DESCRIPTION
       Summarize disk usage of each FILE, recursively for directories.

       Mandatory arguments to long options are mandatory for short options too.

       -a, --all
              write counts for all files, not just directories

       --apparent-size
              print apparent sizes, rather than disk usage; although the appar-
              ent  size  is  usually  smaller, it may be larger due to holes in
              (<E2><80><98>sparse<E2><80><99>) files, internal fragmentation,  indirect  blocks,  and
              the like

       -B, --block-size=SIZE use SIZE-byte blocks

'字符变为<E2><80><98>，为什么？

Answer 1

通过将您的语言环境设置为UTF-8，您已告诉shell和其他程序将以UTF-8编码的文本输出到终端。但是，您的终端不理解UTF-8，因此显示3字节序列而不是U + 2018的实际符号，“左单引号”。您需要将终端仿真器配置为接受UTF-8输出，或者找到一个输出。

当我将LC_ALL从en_US更改为en_US.utf8时，为什么无法显示多个字符
