Bug 921, add_document_to_string: Fixed the UTF-8 half of the code.

Browse Source 
* Recompute the pos variable for each cell, rather than just once per line.
  This fixes the bug that only the first cell was being examined.

* Moved the bulk of the code outside the "if (frame && data >= 176 &&
  data < 224)" conditional.  This fixes the bug that only frame
  characters were being added to the string.

* If the cell has UCS_NO_CHAR in it, don't add that to the string.

* Call encode_utf8 even for characters that originated from a frame.
  This does not matter yet but will be correct if the function is
  later changed to use the Unicode line-drawing characters for frames.
