i have written the text directly to the file and it is stored the text as தமிழ்தமிழ் (some square brackets), but while reading from DB since it is returning as ?????????? the file has been return as ??????????. How ca开发者_如何学运维n i read from DB correctly the text as it is.

Try sending the following query after connecting to the database:

If you're on mySQL < 5.0.7:

mysql_query("SET NAMES utf8;");

if you're on a newer mySQL:

mysql_set_charset("utf8");

AND

 header('Content-type: text/plain;charset=UTF-8'); 

Try to execute 'SET NAMES utf8;' before the reading table.
