Why am I getting question marks instead of Tamil characters when displaying Unicode data in PHP?

Displaying Unicode Data with PHP

Unicode encoding is essential for representing characters from different languages in computing. When displaying Unicode data in PHP, it's crucial to ensure proper encoding to avoid garbled characters.

In this instance, the table contains Unicode data in Tamil. However, the output is displaying question marks instead. To address this, it's necessary to set the character encoding for the MySQL database connection.

The solution involves adding the following lines after the mysql_connect function:

<code class="php">mysql_query("set character_set_client='utf8'");
mysql_query("set character_set_results='utf8'");
mysql_query("set collation_connection='utf8_general_ci'");</code>

These statements explicitly set the character set to UTF-8, allowing MySQL to handle Unicode data correctly.

By setting the character encoding, PHP can interpret and display Unicode data as intended, ensuring that Tamil characters are displayed properly in the output.
