Years later, this question still has top results on Google when looking for unicode whitespace characters. devio's answer is great, but incomplete. As of this writing (October 2017) Wikipedia has a list of whitespace characters here: https://en.wikipedia.org/wiki/Whitespace_character
多年后，这个问题在寻找 unicode 空白字符时仍然在谷歌上获得最高结果。devio 的回答很好，但不完整。在撰写本文时（2017 年 10 月），维基百科在此处提供了一个空白字符列表：https: //en.wikipedia.org/wiki/Whitespace_character
This list has specifies 25 code points, whereas the currently accepted answer lists 18. Including the seven other code points, the list is:

Unfortunately, it doesn't give UTF-8, but it does have the character in the web page, so you could cut and paste into your editor (if it saves in UTF-8). Alternatively, http://www.fileformat.info/info/unicode/char/180E/index.htmgives UTF-8 (replace "180E" with the hex UTF-16 value you are looking up).
不幸的是，它没有提供 UTF-8，但它确实在网页中有该字符，因此您可以剪切并粘贴到您的编辑器中（如果它以 UTF-8 格式保存）。或者，http://www.fileformat.info/info/unicode/char/180E/index.htm提供 UTF-8（用您正在查找的十六进制 UTF-16 值替换“180E”）。
This also gives a couple extra characters that @devio's excellent answer misses.
这也提供了@devio 的优秀答案遗漏的几个额外字符。
