hmm… so far I know, does these setting force to use charset utf-8 ( means a lots more possible characters ). I recheck possible posts you mentioned and seen only that an possible existing flight-plan might get a problem. I assume thats the same “may be” thing what can happen what I had in mind about that setting - an ‘older’ application write then utf-codes instead ‘chars’. But this is nothing I expect for normal applications and I would assume that these setting should not cause issues.
