Mail form doesn't send Russian/Cyrillic characters correctly?

Posted on 16th Feb 2014 by admin

When someone enters foreign characters (like Cyrillic text, and Japanese/Chinese probably gives the same problem) into the mail form, the email that arrives is all gibberish.

For example this should read "test message from *name*" in Russian.
Тестовое сообщение от Корин

I tried changing the header content-type thing from plain text to HTML but that didn't fix it.

The script I'm using is one I found online for free (eternal thanks to its author some of the lines are in Dutch)

Does anyone know how to let the form accept foreign characters? Thanks a lot in advance !!
