Can't use Cyrillic letters.

This is a core limitation that can’t be fixed because Cytillic characters get translated into unicode, I believe. The unicode representation is greater than 20 characters.

Yea, I know, so there is no way to change it? Can’t believe!

Not at this time, my apologies.

Maybe you increase maximum lenth of value from 20 to 500? I can use Cirillc in all other values, exclude name.

It’s a problem with WordPress’ post table schema, not this plugin.

Understood, thank you.
