This thread is resolved. Here is a description of the problem and solution.
Problem: Menu auto scroll with a one-page theme is not working with Chinese characters.
Solution: From the client's description, I can assume that the menu is using the Visual Composer section name to implement this by inserting the name into the data-name attribute of the Div element to target. And what happens with Chinese characters is that they are encoded, and it is not working. The client's workaround is to use English characters for the Chinese section's name. Then it works.
