How to force Cyrillic font characters to be displayed on the site?

Question

css

The font is connected, but only Latin is displayed, while Cyrillic is displayed in a standard font. The font must support the Cyrillic alphabet in the preview, it is . The font is displayed normally if it is installed in the system, but this option is not suitable for the site. When viewing a font that is not installed in the system in Windows 7, Cyrillic is also NOT displayed, after installation all the rules.
I connect like this:

@font-face {
  font-family: 'AG_Benguiat';
  src: url('../fonts/agbenguiat-webfont.eot');
  src: url('../fonts/agbenguiat-webfont.eot?#iefix') format('embedded-opentype'),
  url('../fonts/agbenguiat-webfont.svg') format('svg'),
  url('../fonts/agbenguiat-webfont.woff') format('woff'),
  url('../fonts/agbenguiat-webfont.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
}

How to fix?

Answer 1

The solution is next. You need to edit the font (I did it with the help of font creator based on this article allnokia.ru/hub/kcenter/view-157.htm )
The bottom line is to add the missing Cyrillic characters, and copy the glyphs of the existing ones into them, but located in another areas.
Further, following the advice of @rOOse , we distill the resulting font into the formats of interest with Cyrillic support.

Answer 3

Use google fonts https://www.google.com/fonts
And that's it! small fonts are not readable in a pixel grid, so less than 12px this PT Sans is still somehow readable. And with serifs it would be kapets.
