Disadvantages:
I have been confused all the time. The problem I haven't solved all night is that the first space to be inserted at the beginning of the editor! Error always prompted! It seems to be related to the XML specification!
It seems that c2a0 will become garbled characters in the space obtained by the ueditor. In this case, \ u00a0 does not know how to handle this problem.
The server cannot be filtered! The customer's filtering is not good yet! Please check out ....
