The HTML that the given string results in is <td>FQH<k$/[3:9DxL+!</td>
which the browser tries to interpret as an HTML and the result is this: <td>FQH<k$ [3:9dxl+!<="" td=""></k$></td>.
As the <k$> element has no text, it is not visible on the page.
The solution to this is setting the HtmlEncode property to true for the column that contains such strings.
