Document cannot be saved if forbidden characters pasted

I speculate that there are some things that should not be pasted into the
formula editor. While no immediate damage is felt, the lurking deadly side
effect is that the document cannot be saved. It may not be apparent at that time
as to what the cause is, and work may be lost if user discards all modified
content in frustration.

* Open open office writer
* goto menu Insert->Object-Formula
* Type "a  b" without the quotes
* now open in acrobat reader
http://www.tug.org/tex-archive/info/symbols/comprehensive/symbols-letter.pdf
(just about any character that you think has been copied will do)
(for purposes of issue reproducibility)
goto Page 32
select the character corresponding leftrightarrows
* Paste that in between a and b as "a # b" where # might actually even not be
visible
The user may know that the paste itself was not successful as expected, however
apart from an extra space nothing is visible in the the formula editor. Things
seem to go without error.
* Proceed as though everything is normal
* click back into writer
* Try to save the document
You get the error dialog box
"Error saving the document test.odt:
Write Error.
Error writing file.
OK"

Suggesting, that 
   1)pasted text be filtered for forbidden characters
or 2)prevent the paste with a message box indicating why not feasible
It is very imperative that in fixing this bug that
  pasting Unicode characters from
http://en.wikibooks.org/wiki/Unicode/Character_reference/2000-2FFF is allowed

Note that this issue rises because one wants easy way to get character
The symbol catalog is not very user friendly 
and there are insufficient characters predefined (issue 46571)
