How to deal with garbled Chinese characters displayed by ICEcoder

I saw this little thing called icecoder on the Internet. It is a web-based editor and it is very good. The only disadvantage is that the Chinese characters in the opened file will become garbled.

After checking the source code, in lib/file-control.php, line 89 is:

echo ''.htmlentities($loadedFile). '<script>';</span></p> <p>It turns out that htmlentities will turn Chinese characters into garbled characters and replace them with htmlspecialchars with similar functions: <br><span>echo '</script>'.htmlspecialchars($loadedFile).'
