a related bug is 304364.

To reproduce the problem:
- open the controls demo, table tab, and change the text value 
  of a table cell using widgets on the right hand side to a string 
  that contains the unicode codepoint: 2028
    (tip: on windows, by setting a registry key 
	(http://en.wikipedia.org/wiki/Alt_codes#Unicode_characters), 
	you can easily input this character by pressing ALT + "+" + 2028)

Note: this semantic line separator character is sometimes found 
      on websites, e.g. in the impressum, at the end of the line. 
	  After copying this text to a RAP application, 
	  where it is processed and displayed in a table,
	  this error happens.

The reason for this problem is that the resolution of bug: 304364 
did not fix this issue in the table.

Proposed solution:
In TableItemLCA#writeTexts, use WidgetLCAUtil.escapeText to escape
the text. That method correctly handles the "NonDisplayableCharacters",
that the private #encodeHTML method did not do. 
Because WidgetLCAUtil.escapeText performs all the transformations
that #encodeHTML did, it is safe to replace it.

Note: 
the call to WidgetLCAUtil.escapeText is there, 
but commented out in the source code.
Browsing the project history, I found that the commit: 4ad7ae62
(git mirror) introduced this change, on May 25 16:33:12 2007.
Although the comment states it does not work with escape text,
I think this information is deprecated and could not think of any reason,
why it would not work.
Just uncommenting this line seems to resolve the issue, without
side effects.
