Question : Simplified Chinese grabled in Lotus Notes

We have an application, coded in Perl, that sends reminder emails to it's users.. The text for these emails is stored in a database and the email headers are generated automatically.

We are finding that some Lotus Notes users based in China are recieving the messages either with garbled headers or, very occassionally, completely garbled.

By default, the email header contains:
Content-type: text/plain; charset=UTF-8;

but we have also tried with:
Content-type: text/plain; charset=CN-GB;

These emails appear fine if sent to users with Outlook 2003 or 2007.

Is there anything we can do to make sure these emails display correctly for all Lotus Notes users?

Answer : Simplified Chinese grabled in Lotus Notes

Two possibilities:
1. the mail format isn't correct
2. their Notes installation isn't correct

To tackle the problem, can you ask them to save the HTML-source of both your mail and a correctly received MIME mail, and send that to you, so you can verify the correctness of the formatting?
