I use php to read chinese from sql server and display it in the web page by using php. The page code is encoded as 1m 8, and the page source code file is encoded as 1m 8, and I use the mb convert encoding function to convert the read to utf8 in the chrome. But under ie8, you can display chinese, but there's a black dot behind the chinese, but there's no black spot to look at the source code. What's this reason. Thank you.
