These type of problems are quite common and happen in situations where, for instance, the character set on client (regional settings) clash with the email character set, which is UTF-8 in this case.

You may try switching language in your phone to English, if it was not already, to see if it helps. In this case you should recreate this email user account on your phone, as the email client doesn't necessarily store the email in the original form it came in.

Some years ago the problems were common mainly with HTML content type emails, but lately I've seen a lot of problems with plain text emails, such as this.

Other possibility might be that the server end at your provider (nokia?) may have been "optimized" for only a handful of phone device clients. Optimizing means here that the server software provider may have had to go against email standards to get, say, Windows Phone clients to work properly. This could be possible because Windows Phone clients do not do plain text UTF-8 email messages very standards compliant. I've been troubleshooting such case myself...

Does this account use IMAP or ActiveSync?
