The following exception occurs when a tryinf to resave workbook containing a name area with characters with accent (like french ones) in its name and a comment OR no accent in the name but one in the comment.
(the following case : characters with accent in the name and no comment, works well)

Exception in thread "main" java.lang.RuntimeException: Buffer overrun

Java code : just open the test file and resave it with POI.

The write logic was incorrect for non US-ASCII strings (read logic was fine). Fixed in r1099313.
