some questions using the stopwords

[qiaopolyu]

Hi, thanks for sharing. I have used it to delete the stopwords. using zh.txt. However, certain words listed in the txt are not deleted. some are deleted. For instance, I want to delete "不“ (no) But some "不”（no) remains and some are deleted. and i wonder why. And i also want to ask: do we need to do word-segmentation before delete stopwords? I do, with Jieba. But I want to ask some more suggestions.
