In = normal text, you see at least a word, and usually a sentence. Those give you enough context to know it=E2=80=99s not a Latin =E2=80=9Ca=E2=80=9D. > > It is when you are proof-reading text that it becomes important to > > distinguish Latin and Cyrillic, to check that you don=E2=80=99t have = a stray > > Cyrillic letter within an English word, or vice-versa. > > If I want to check which kind of a it is, I can do that with C-x =3D. You can do that if you already suspect one letter to be of the wrong alphabet (e.g. your spell-checker tells you there is no such word as =E2=80=9Cs=D1=80ell-=D1=81hecker=E2=80=9D). You cannot do that for any reas= onably long stretch of text. > It would never occur to me to test "Is this really a Cyrillic a" > by searching for a Latin a and seeing if that finds it. Neither to me, though I might use a regexp isearch for [a-z] to highlight all Latin letters in a paragraph where I expect none. It would be confusing and misleading if it highlighted [=D0=90=D0=92=D0=95=D0=9A=D0=9C=D0=9D=D0=9E=D0=A0=D0=A1=D0=A2=D0=A5=D0=AC= =D0=B0=D0=B2=D0=B5=D0=BC=D0=BE=D1=80=D1=81=D1=82=D1=83=D1=85].
