VIM plugin NERDTree unable to handle subfolder name with matching parenthese -

i met problem nerdtree plugin while using vim. seems nerdtree cannot handle folder properly, if there matching parenthese in folder name, such "[d]2015", "(t)", "foo[bar]", etc..

i can view containing files o or x command on parent folder within nerdtree window, while o , x on folder have no effect. if stay within nerdtree window, find no way access/edit files in such folder.

i can reach contents in such folder using ":explorer" netrw, or using command-line or external shell. however, wonder if there tricks fix problem within scope of nerdtree.

i met problem on win7 (32bit) first.
nerdtree plugin zip clone of latest version(4.2.0) repository on github, last modified @ 2014.11.20.
vim version 7.4, 1 vim's offical website. beginning of version info follows:

vim - vi improved 7.4 (2013 aug 10, compiled aug 10 2013 14:38:33)
ms-windows 32-bit gui version ole support
compiled mool@tororo
big version gui. ...

i checked on ubuntu-14.04 (64bit) , found same problem nerdtree.

i read nerdtree's reference manual , found information in change log of 4.1.0, bugfixes part:

• fix win32 path escaping issues. stephan baumeister, ricky, jfilip1024, , chris chambers

but not sure whether relevant or not.

by way, option nerdtreehijacknetrw makes me confused. let "g:nerdtreehijacknetrw=0" seems have no effect.
