Reading/displaying stored data should not change the stored data! You
should determine what internal data storage format you want and keep it
consistent. When you retrieve data for presentation/display you can
reformat the data prior to display (eg. for localization), but you should
not overwrite the stored data with the new format (this will cause you
serious difficulties as your data 'reading' routines will never know what
format the data is stored in - unless you also store some formatting
information, but in most cases this is a bad idea!)
