those 7-bit ASCII output is non identifiable to human. Normally I use ascii2uni -a K to convert into UTF8. but in Fedora 25, the uni2ascii is not in repo. So any other way to make it output UTF8?

Answer 1

I found another answer on StackOverflow. Making changes to my locale settings didn't help at all, but using the -N option with tree did.

# tree -if ./my-path/
./my-path/Olaf\ Hund\ Vs\ Ursari\ De\ Clejani\ _\ Taraf\ De\ Hai210円douks\ _\ Koçani\ Orkestar\ -\ electric\ gypsyl.mp3
# tree -ifN ./my-path/
./my-path/Olaf Hund Vs Ursari De Clejani _ Taraf De Haïdouks _ Koçani Orkestar - electric gypsyl.mp3

Note that this also un-escapes spaces.

• eexpress: It's 2 years post, fc31 is OK now. No need -N or any other command switch.
• Pavel Lishin: What is fc31? Another command line tool?
• Sun Junwen: -N fix Chinese issue.

Answer 2

Set the encoding to UTF-8 (and choose an appropriate locale that has support for Unicode) e.g.:

LC_ALL=en_US.UTF-8 tree -L 1 下载

Presumably you are using a locale that can not interpret those characters (C maybe?).

Example:

% LC_ALL=C tree 下载 
344円270円213円350円275円275円
`-- foo
% LC_ALL=en_US.UTF-8 tree 下载 
下载
└── foo

• eexpress: LC_ALL not work at all. all LC_* except LC_ALL is "zh_CN.UTF-8" in locale. paste.fedoraproject.org/paste/…
