dear Andy and all,
while waiting for any respond from the group, I try to debug and get
better understanding about it. I stripe everything and start with one
column of data. I got a new understanding. The error was caused in the
sql query statement. In the SQL query statement, there is "? mark, wrong
concat (it is my mistake to put in the wrong way).
Now, it is showing the JSON data in the browser console, not in the
browser page. I am still looking for how to do it.

You may want to give us the entire error msg. If it's saying an
invalid char, it may be an actual non-ascii char in the text of the
program, not necessarily from the data, though that might depend upon
how you're displaying the data.
