white space to &#0???

I am using JTidy to convert HTML to XHTML and it seems to be converting some
white space to &#0 which is not a valid character reference.  Is this a bug?

Here is a fragment of the code before tidying:

<B>Live Traffic</B></FONT></A>   &nbsp;</td>

Here it is after tidying:

<b>Live Traffic</b></a> &#0;&#0; &#160;</td>
