Xcode 4.0 中的空间问题
昨晚我在检查新功能时安装了一个新的xcode。文件名旁边、最右侧编辑器上方有一个锁定图像。我点击了那个锁，然后我注意到空格被一些未知的字符替换了。我附上了下面的图片。现在我怎样才能删除这些字符并使其成为正常空间。如果有人能帮助我解决这个问题，那就太好了。
提前致谢
I have installed a new xcode last night when i was checking for new functions. There was a lock image next to the name of the files and above the editor on the right most side. I clicked that lock and then i noticed that the space is replaced with some unknown character. I have attached the image below. Now how can i remove these characters and make it normal space. If anyone can help me out with this it will be great.
Thanks in advance

I usually do that, so I can quickly see if I have tabs or spaces, for instance...
