Some eight years ago UTF-8 (Unicode) became the most used encoding on Web pages. At the time, though, it was used on only about 26% of Web pages, so it had a plurality but not an absolute majority.
Note that the 2008 crossover point appears different in the latter two Google graphs, which is why I’m showing all three graphs rather than just the third.
A different source (with slightly different figures) provides us with a look at the situation up to the present, with UTF-8 now on 85% of Web pages. Expansion of UTF-8 is slowing somewhat. But that may be due largely to the continuing presence of older websites in non-Unicode encodings rather than lots of new sites going up in encodings other than UTF-8.
