I have seen some of the title of websites includes numbers like ஐ, ♦, ♦, ♦ etc. <title>ஐ Website Development NewAgeSMB is a complete Website Development service provider company offering website development </title> Anybody knows why and what is the purpose of using this numbers in to the title tag.
Not sure what ஐ is, but ♦ is the HTML character code for the Black Diamond character. It shows up as a number in the Title bar because the title tag won't convert special character codes into the special characters. Thus, the title of the page might show up as ♦ All about Black Diamonds ♦, while the page itself shows (black diamond) All about Black Diamonds (black diamond). See wikipedia for other such codes: http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references
Its a tamil (Indian language) letter & its character code is 0B90. It may possible that you have outsourced your work to any Indian Company, who have this code in their Dynamic Web Designing Program.
Please search on Google for wholesale rhinestone belts and first result is http://www.besthandbagwholesale.com/ On that site it is displayed.
Its nothing serious. It would probably help if those characters were gone (all I see is a box which tells me I don't have the right character set), but it won't really hurt anything. Its the same thing as when you see the hampersand code (& in a title. A little confusing to the uninitiated, but I doubt it would scare a customer away.
