Emacs doesn't open fonts it considers for a given character, to avoid a long delay when many fonts are tried (opening a font is expensive). Without opening a font, it is impossible to know with 100% certainty whether a font that declares coverage of some range of characters indeed includes a glyph for each character in that range. > On my Emacs v 25.0.50.1 on Kubuntu 15.04, started with -Q and setti= ng > the default font to "Source Code Pro" or Consolas, "Ume Mincho" is = used > for =E2=88=80, but with "Deja Vu Sans Mono" as the default font the= re is no > problem. Your Emacs has the problem reported by the OP solved, so the fonts yo= u use not necessarily will solve his problem with Emacs 24.4.
