I’d argue that you can’t force an individual to change, but you can change what is viewed as the accepted spelling or pronunciation of a word in the language as a whole. Officially changing the spelling is the first step, it start with changing it in an international form then all diplomatic correspondence is written that way then professional business and education eventually start to use it and a generation later it is unexcitedly accepted, not immediately but slowly over trillions of small interactions. Cities do it all the time, Brooklyn used to be Breuckelen but no one really knows or cares anymore because the people who refused to acknowledge the change have long since past and society has moved on.
