UNICODE accented vowels for Russian

I have just discovered that my posts to this blog are unable to display accented Russian as in displaying

Еврейская автономная область

as

Евре́йская автоно́мная о́бласть

which should have appeared with accents over one vowel per word as high-lighted below:

Еврейская автономная область

as an aid to pronounciation for foreigners and as disambiguation of some words for Russians themselves.

The editor for blogspot shows no sign that there will be a problem.

To test, be sure that your browser's encoding option is set to at least utf-8.
