Enable terminal colorized output and print out chinese character

$> man ls
.....

-G      Enable colorized output.  This option is equivalent to defining
             CLICOLOR in the environment.  (See below.)
-w      Force raw printing of non-printable characters.  This is the
             default when output is not to a terminal.

If you want terminal can display chinese character and colorized output, you should add a line to ~/.bashrc or ~/.profile or ~/.bash_profile:
alias ls='ls -wG'
or:
alias ll='ls -lawG'
