What is the general etiquette about about using the newer characters （新字体） or even a more modern version of the old character (旧字体） when used in names? Is it generally considered rude?

For example, my partner's family name is 濵 which is often somewhat problematic to type into a computer and so I often see it just replaced with 濱 (you might have to look close to see the difference) or sometimes even with the new character, 浜.
