The notation referred to uses a "vinculum", a line over a digit. Thus, this
would be a job for combining macron or combining overline rather than
combining dot above.

The results inevitably depend on the font and on the browser, when combining
diacritic marks are used.
The approach of using text-decoration: overline or border-bottom give more
consistent results.
But a notation like 0.333... is probably best. It's reasonably
self-explanatory and clear and requires no special techniques. You can use
the horizontal ellipsis character instead of "..." to get better typography,
but the result depends on the font.
