Rails - humanize for Cyrillic not working?

Question

Ruby on Rails

Dear Railroaders!
I was surprised to find that the simplest humanize method (as well as titleize and apparently other similar ones) does not work for Russian words. Google is silent on my numerous queries like a fish.
Here is an example in the console:
2.2.2 :002 > "example".humanize
=> "Example" (everything is ok)
2.2.2 :003 > "example".humanize
=> "example" (mystic...)
"russian" " is installed (although it seems to have nothing to do with it). The locale is configured: config.i18n.default_locale = :ru
Friends, I'm at a loss, help me out!

Answer 1

Try this: "example".mb_chars.titleize

Answer 2

mb_chars
