@deceze and @Shakti thanks for your help.

+1 for the article link posted by deceze (Handling Unicode Front to Back in a Web App) and it also worth reading Understanding encoding

After reading your comments, answer and of course those two articles, I finally solved my issue.

I have listed the steps I did so far to solve this issue:

1. Added header('Content-Type: text/html; charset=utf-8'); on the top of my init.php file,
2. Changed CHARACTER SET of my database table field which is storing those value to UTF-8,
3. Set MySQL connection charset to UTF-8 mysql_set_charset('utf8', $connection_link_id);
4. Used htmlentities() function to convert characters $meta_title = htmlentities(trim($meta_title_raw), ENT_QUOTES, 'UTF-8');

Now the issue seems to be solved, BUT I still have to do following thing to solve this issue in FULL.

1. Get the encoded charset from the source $source_charset.
2. Change the encoding of the string into UTF-8 if it is already not in the same encoding. For this the only available PHP function is iconv(). Example: iconv($source_charset, "UTF-8", $meta_title_raw);

For getting $source_charset I probably have to use some tricks or multi checking. Like checking headers and meta tag etc. I found a good answer at Detect encoding

Let me know if there are any improvements or any fault on my steps above.
