Why my website is showing junk characters? My Drupal 6 website is showing junk characters like:

&lt;�h�3�>�C�o�m�m�e�n�t�s�&lt;�/�h�3�>� �&lt;�t�a�b�l�e�>�&lt;�t�r� �b�g�c�o�l�o�r�=�'�#�E�7�E�7�E�F�'�>�&lt;�t�d�>�P�o�s�t�e�d� �O�n�:� �1�2�-�1�3�-�2�0�1�0� 

It used to happen once in every 1-2 months, and with any page of the website. Clearing the cache resolve the problem.
I think its the problem with cache_page table and page compression, because when I manually clear the entry in cache_page table for that particular page, it gets resolved.
When we remove � manually, we see:

&lt;h3&gt;Comments&lt;/h3&gt; &lt;table&gt;&lt;tr bgcolor='#E7E7EF'&gt;&lt;td&gt;Posted On: 12-13-2010


Probably it comes from comment.tpl.php in your theme. At first glance looks like UTF-8 - UTF-16 issue, but only you can really debug that.

The exact part of code you pasted seems to appear in following threads:

See, maybe original developer was using them? Hope it helps you with debugging, we here cen't really help more.
