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?

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\ Hai\210douks\ _\ 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.

  • It's 2 years post, fc31 is OK now. No need -N or any other command switch.

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?).


% LC_ALL=C tree 下载 
`-- foo

% LC_ALL=en_US.UTF-8 tree 下载 
└── foo
