Mess with Cyrillic variation names

We got a mess in variation names on Cyrillic since the last update (3.0.1) — they typed in URL Encoded format (the screenshot — https://thecorewp.com/tmp/wpc_vb.png).

Downgraded to 2.5.6.

Here is Cyrillic text if you need it to test the plugin:

• Название товара (Product name)
• Названии вариации (Variation name)
