There is at least one more situation where different glyphs could/should be selected for the same Unicode code points, which charset markup does not solve. I=E2=80=99m talking about italic shapes of Cyrillic letters. For some of th= em, Russian and Bulgarian use one shape but Serbian and Macedonian use another shape[1]. There are no examples of Bulgarian, Serbian, or Macedonian in HELLO, but Russian, Ukrainian and Mongolian examples are all marked up as =E2=80=9Ccyrillic-iso8859-5=E2=80=9D, which is an encoding= that does not carry language information. So: charset markup is not the right solution to the problem of rendering the same Unicode code point with different glyphs.
