In Dutch we also have the letter IJ which is part of my last name. But ASCII (nor EBCDIC) don't have it so some family members have changed it to 'y' and some are using 'ij' to make up for that. So on paper our family lineage is now split because these changes have meanwhile made it into birth certificates and legal names and it's so ingrained that it can't really be changed any more.
