在ubuntu的docker镜像中，给vim安装了NERDTree插件，但是本来目录左侧应该显示“+”，但是变成了“�~V�”，而且无法打开目录。
解决方案：
编辑NERD_tree.vim文件，把
if!nerdtree#runningWindows()&&!nerdtree#runningCygwin()
calls:initVariable("g:NERDTreeDirArrowExpandable","?~V?")
calls:initVariable("g:NERDTreeDirArrowCollapsible","?~V?")
else
calls:initVariable("g:NERDTreeDirArrowExpandable","+")
calls:initVariable("g:NERDTreeDirArrowCollapsible","~")
endif
改成：
"if!nerdtree#runningWindows()&&!nerdtree#runningCygwin()
"calls:initVariable("g:NERDTreeDirArrowExpandable","?~V?")
"calls:initVariable("g:NERDTreeDirArrowCollapsible","?~V?")
"else
calls:initVariable("g:NERDTreeDirArrowExpandable","~")
"endif 原文链接：https://www.f2er.com/bash/387782.html
