It's because callback of WKPageGetContentsAsMHTMLData returns WKData, which is not null-terminated string, but it is considered as common string.
We should pass null terminated string instead of WKData.

It doesn’t make sense to take this data and convert it to UTF-8 as if it was Latin-1. If you want to put it in a CString so it gets null terminated, then I suggest creating the CString directly, not through a String.

Thanks, I updated to use CString.
