问题描述：pod install 更新时老提示检测到中文引号

[!] Smart quotes were detected and ignored in your Podfile. 
To avoid issues in the future, you should not use TextEdit for editing it.
 If you are not using TextEdit, you should turn off smart quotes in your
 editor of choice.

用Xcode打开podfile文件后，查找异常的中文符号，奈何字体问题，很不明显。。。

小技巧：
查找英文 ' 或中文引号字符 ‘
一目了然！
