Error sending email when customer's name contains non-standard characters

[whisper]

Hi,
I'm sure that it's not only my problem:

If the customer's name is e.g. John Smith, everything works fine. BUT if the customer's name is something like Štefan Novák (which is common in Slovakia / Czech republic etc.), the system will not send emails to the customer from the Orders page in Back Office.

The error displayed says something like "1 error occured while sending email". I'm using default PHP mail() function and as I said, for contacts with simple names it works fine...

I'll be very thankful for any help.

The same issue for me... Have you found a sollution ?

OK, I think I solved this: in classes/mail.php change line 55:
$to = new Swift_Address($to, $toName);
to
$to = new Swift_Address($to);
So, it will not add email owners name and surename (those may be non-standard characters) in front of mail adress.
