I saved some accented and umlauted characters in a plain txt file using mac with UTF-8 encoding under a dropbox folder, and when opening it using dropbox in a browser or on an ios dropbox app, the acccented characters are incorrectly displyed, i.e. ignroed or replaced with something wierd. Conversely when I saved a plain txt file with accents using ios dropbox app, the plain text file opens in Mac Textedit with incorrect accents. Is there a way to set the plain text file so that accents and umlauts are interepreted correctly on both my Mac and dropbox app/online viewing through a browser?
