It would be a valuable contribution if you generate two worksheets
containing strings with \u00a0. One with SXSSF and the other with
XSSF. You can use my code snippet. Then unzip the files, compare and
figure out what's wrong with handling \u00a0 in SXSSF.
You want to look at sharedStrings.xml and sheet1.xml.
