Does > Emacs make assumptions about number of columns per line? It does, but the number of columns doesn't change, only the width changes. Right? What Emacs expects is that the terminal emulator will space characters according to the width in columns (either 1 or 2) of each character, as defined in the Unicode Character database. You can see what Emacs thinks about the width of each character by using 'char-width'. AFAIR, all emoji should have width of 2, is that right?
