Linux“man”页面在 CentOS 中显示为乱码

Question 1

我建议检查一下/etc/sysconfig/i18n：

该/etc/sysconfig/i18n文件设置默认语言、任何支持的语言和默认系统字体。

有一个更大规模的讨论man，且可能存在字符损坏在这个网站上讨论类似的事情。有趣的是man.config位于此处的文件的讨论：

/etc/man.config

我使用 Ubuntu — 因此在我的系统上找不到该文件；manUbuntu 上的设置与 CentOS 不同 — 但所显示的示例显示了两行我认为与此相关的内容：

COMPRESS /bin/gzip
COMPRESS_EXT .gz

在我看来，您所描述的逻辑就像man屏幕上显示的原始压缩文件。所以也许解压过程中的某些东西搞砸了一切？

Question 2

这是 CentOS6 的“好”内容/etc/man.conf，以防有人进入这种状态（即某些东西被抹去/etc/man.conf，你因为无法阅读手册页而陷入困境！）。谢谢@Giacomo1968 的回答为我指明了正确的方向。在本例中，解压缩程序是lzma。

#
# This file is read by man to configure the default manpath (also used
# when MANPATH contains an empty substring), to find out where the cat
# pages corresponding to given man pages should be stored,
# and to map each PATH element to a manpath element.
# It may also record the pathname of the man binary. [This is unused.]
# The format is:
#
# MANBIN                pathname
# MANPATH               manpath_element [corresponding_catdir]
# MANPATH_MAP           path_element    manpath_element
#
# If no catdir is given, it is assumed to be equal to the mandir
# (so that this dir has both man1 etc. and cat1 etc. subdirs).
# This is the traditional Unix setup.
# Certain versions of the FSSTND recommend putting formatted versions
# of /usr/.../man/manx/page.x into /var/catman/.../catx/page.x.
# The keyword FSSTND will cause this behaviour.
# Certain versions of the FHS recommend putting formatted versions of
# /usr/.../share/man/[locale/]manx/page.x into
