Example of encoding problem

After days of research done by our team member Weikiat, we have finally found the solution to solve the Unicode problem. Earlier, websites with pages in Unicode encoding such as ‘你好吗’ was messing out. Apparently, this line was not recognised:

<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″ />

For .html files to auto display unicode characters, you have to add following line to htaccess.

AddType application/x-httpd-php .html

Basically, it will treat html file as php, as unicode will display correctly in php files.
