Get a 62.5% more program space easily

with the previous link, it will take the same code space (+/- few bytes) and you'll never have to translate your strings. Make things really much easy when you need to modify or add any strings.

Another idea is to save your string (or part of) in the internal EEPROM. Using your method or a variant of will permit to store 256 character in the internal EEPROM. I don't know how your string eat space but it could work too.
