Commented Unassigned: GetValue returns empty string for cells in some xls files [11928]

I'm having trouble using GetValue on some xls files. The attached file is one example. GetValue returns an empty string for virtually all text fields (including A1). Looking at the DataTable generated through AsDataSet also has the fields empty when they do in fact have text.

It looks like there is some issue with XlsBiffSST in the ReadStrings method. Using the attached spreadsheet, one of the strings ends up looking like this:

"˦\0\0\0Block B,4/F., Winful Industrial Building, 15-17 Tai Yip Street, Kwun Tong, Kowloon, Hong "

This means that the next string that is parsed ends up looking like this (truncated), which is actually several strings:
