After upgrading to 5.3-rc-1, all my templates are not parsed successfully. The error message points to the line where there are Chinese words.

Stack Trace below:

解决方法：
This means that the byte stream is converted from the system encoding to UTF-8 and then back. During this transformation a number of characters are wasted. In my case the solution would be the following:
337: InputStreamReader rawReader = new InputStreamReader(rawStream, "UTF-8"); // used UTF-8 charset
341: PrintWriter writer = new PrintWriter(new OutputStreamWriter(bos, "UTF-8")); // used UTF-8 charset
