Invalid byte 1 of 1-byte UTF-8 sequence

This is a very common problem, that is, the UTF-8 XML file is default to GBK or other encoding of the editor after the change is saved to another encoding, the solution online a lot.

In fact, the need to note is not convenient for the diagram, casually find an editor to save and then submit.

and the number of lines of error is generally not easy to find, I think, look at which file there is garbled, it is good to locate (others submitted by different encoding files, often because of the Chinese into garbled characters will lead to this problem.)
