Using this sql:

SELECT similarity('Круиз-контроль отключен', 'Круиз-контроль отключен');

work well on Linux and Windows and the result is 1: on OSX the result is
NaN.

Thanks

SELECT similarity('КруОз-кПМтрПль ПтключеМ', 'КруОз-кПМтрПль ПтключеМ');
work well on Linux and Windows and the result is 1: on OSX the result is
NaN.

I couldn't reproduce that on my own Mac. I tried it in ru_RU.UTF-8 and
en_US.UTF-8 locales --- perhaps you are using something else?
