Problem with utf-8

How did you make the Armenian form and what letters get garbled? Can I check the site?

When I click add form I choose the language Armenian, it bring automatically the form but when I save it I got ??? marks instead of the letters. Here is the link : https://myschool.am/??????-???????????/?????????-??????-??????????

And at the same time I got empty < Message body: > and the translated massages I got the English version not the translated variants.

Try deactivating all other plugins and switching to the default theme. If it’s difficult now, try deactivating WPML at least.

I am using WPML for multilingual purpose. I am running it on my PC server with the same plugins (even more) and theme as well and have no problem. I think this is a cause of database charset. Does the plugin make table in the database?

No, Contact Form 7 doesn’t make a table.

Does the plugin keep some data in option table in database and is there any other solution for this problem except disabling other plugins?
