I can't quite put my finger on this one, but there definitely seems to be something strange with the exclamation mark emoticon . Under some circumstances it will get interpretated as part of an image link. In the following snippet Confluence tries to render the first as an image link:

	!
	?
	!

Result:

<table class="confluenceTable">

<td class="confluenceTd">(<img src="/confluence/download/attachments/1094/%29" align="middle" border="0"></td>

<tr>
<td class="confluenceTd"><img class="emoticon" src="/confluence/images/icons/emoticons/help_16.gif" alt="" align="middle" border="0" height="16" width="16"> </td>
<td class="confluenceTd">?</td>

<td class="confluenceTd"><img class="emoticon" src="/confluence/images/icons/emoticons/warning.gif" alt="" align="middle" border="0" height="16" width="16"> </td>

<td class="confluenceTd"> !</td>
