Nokia barcode reader not working with Zs

The nokia barcode reader (as tested on E90 and N95 and other models) does not work with IEC16022 (datamatrix) barcodes that contain Z or z in TEXT, X12 or C40 format.

E.g. try reading

http://mobilecodes.nokia.com/dm?BARCODE=zzz&X=0.18&name=&type=link&MODE=...

My E90 is V 07.40.1.2 03-10-2007 RA-6 NokiaE90 213.03

Problem is that even if fixed in later releases it means you cannot reliably use barcodes that have Z in them as many people will have old an broken versions of the reader.

This rather limits use of barcodes.
