Feed Reader is not recognizing the close tag of CDATA


I am trying to wrap a figure within CDATA. When I see the feed in the FeedReader, I can see that the close tag of CDATA which is "]]>" is getting displayed in the Feed.
Output looks something like this:
Title of the Feed
Date Created

"some text getting displayed"

"Figure getting displayed"

]]>

When I see the source code it looks something like this
]]>

Kindly help me resolve this.
