Nerd tree: enter does not open sub dirs

Question

I installed NERDTree via Pathogen on Mac OSX 10.6.8.

When I vim a dir, I cannot enter into sub dirs with enter key. Furthermore, the dirs look like this:

Answer 1

If you'd still like to try to get the arrow characters to work, here is my answer from Why does my nerd tree have these odd characters. I run Arch Linux, so your mileage may vary.

I had this exact same problem and was able to fix it by uncommenting UTF-8 and leaving ISO-8879-1 commented out in /etc/locale.gen. Then I ran locale-gen and restarted. Also added 'export LANG=en_US.UTF-8' to my .bashrc. Here are the results of my locale settings once it started working:

[lysistrata@(none) ~]$ locale -a
C
en_US.utf8
POSIX
[lysistrata@(none) ~]$

Answer 2

I'm using RedHat 6.1 and vim 7.3 and had to recompile vim with multibyte support.

$ cd ~/src && wget ftp://ftp.vim.org/pub/vim/unix/vim-7.3.tar.bz2
$ tar xjf vim-7.3.tar.bz2 && cd vim-7.3
$ ./configure --enable-multibyte
$ make
$ sudo make install

Then verify that multibyte support has been enabled.

$ vim --version | grep byte
-arabic +autocmd -balloon_eval -browse +builtin_terms +byte_offset +cindent 
+mouse_xterm +multi_byte +multi_lang -mzscheme +netbeans_intg -osfiletype

Answer 3

Check locale on your system, if output is something like this one LANG=C then do the following steps:

1. sudo echo "LANG=en_US.UTF-8" >> /etc/locale.conf
2. sudo locale-gen and sudo reboot

check your locale again. Hope this can solve your problem.

Answer 4

On Mountain Lion 10.8.2

This worked for me

export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

Answer 5

Putting this in my .vimrc solved the problem: let g:NERDTreeDirArrows=0

The creator gave me the fix: https://github.com/scrooloose/nerdtree/issues/108

Answer 6

I followed jernkuan's answer but didn't work. What worked for me was typing :set encoding=utf-8 inside vim But I lose this when I exit out of vim. I have to do this everytime I am on vim
