TM(Trade Mark) symbol not appearing on Facebook Wall when content containing this symbol is shared on Facebook

TM(Trade Mark) symbol not appearing on Facebook Wall when content
containing this symbol is shared on Facebook

I am Srinivasa. Currently , I am facing an issue with Facebook LIKE button.
I am a developer working for a Company which maintains Online
Webstores. I have implemented a LIKE button on a product page for a
store. But the Customer who is actually using the LIKE button on the
respective Product Page is facing an issue.
The Customer says that when the product is liked using the LIKE
button, TM symbol which is part of the Description of the product is
not coming up properly on the Facebook Wall as part of the feeds
which gets displayed on the Customer's friends'wall. The HTML
code(™) of the TM(Trade Mark) symbol is coming up on the wall
instead of the symbol when the LIKE button is used.
Can any one suggest me, what has to be done to see that the TM(Trade
Mark) symbol shows up correctly when the Content is shared as part of
the LIKE Button functionality. There is a file called
facebookMeta.jsp which sends the metadata to the Facebook Server when
a particular product is liked.
I have tried to replace the HTML code(™) with its equivalent
Unicode of TM symbol.But this is not working.
Please respond to my question asap.
