[dejavuwow]

I updated the plugin just now. but it doesn't work😫
when vim start up，the plugin throw an error like this

the variable g:NERDtreeNodeDelimiter is not defined at nerdtree.vim.
And it causes vim doesn't work now.

[PhilRunninger]

What is the output of the :scriptnames command?

I can't do any opration since the error throw.
vim doesn't respond to me.

If you have something in your vimrc that automatically launches NERDTree, remove that first, and then run :scriptnames. If you can share your vimrc, that would help too.

What happens if you put this in your vimrc?

let g:NERDTreeNodeDelimiter = "\u00a0"

At this point in the diagnosis, it's a workaround, but let's see if it solves anything.

throw error: cant't find separator in line 41

[PhilRunninger]

I wonder if it's the encoding that you're using. Instead of \u00a0 use some other character that you won't find in filenames. This variable is used to separate the filename from the rest of the characters on the line of text.

well，I tried let g:NERDTreeNodeDelimiter = " "
it worked unexpectedly!

[dejavuwow]

emm...it seems to cause another proplem.
i can't open the folder,command output:
NERDTree: cannot close tree root

[PhilRunninger]

The idea behind the latest change (and the \u00a0 character) is to have a better way to get the filename from the line of text in NERDTree. Other things that it needs to remove are the arrow heads, spaces, square brackets, bookmark indicators, symlink indicators, and flags that other plugins may introduce. There is a lot of text to sift through. We were getting reports that people couldn't open files with uncommon characters in them, files like:

foo[bar].txt
 leading_space_filename.txt
trailing_asterisk_filename*
curly{braces}.txt

and so on.

So I decided to use a \u00a0 (non-breaking space) to separate the filename (with whatever characters it has) from the rest of the text. That appears to be a bad choice for your setup. A space won't work either, because they are used to indent the files. Try some other obscure character, and see if that helps.

ok，I tried use tab character.
It has been resolved.
thanks very much!❤
