REST API returen comments with  
Hi, with the following REST API to get comments of one workitem, if the comments has Chinese, the blank space returns with  . I think other special characters also will be transferred. If the comments only contain English, the black space shows well, not as  .

This will introduce more work to deal with the return data from REST API. I want to know why this occur, and is there a way or REST API attribute to get Chinese comments without escaping?

One answer
They are different spaces, one is "non-breaking space", and the other normal "white space". Their codes (in any encoding) are different. Also note that when you use different Chinese input methods to type the "non-breaking space" (全角空格), the codes for the "non-breaking space" can be very different.
As for not escaping the special characters, I don't think it's a good idea since the content has to conform to certain specification.
