[i18n] Question about using Horde for Japanese webmail

[Doug Lerner]

I recently signed up with a hosting provider and they offer Horde as  
their webmail solution.

I am having difficulty getting Japanese email to work completely  
though and would like some advice.

What I have discovered so far helps me to 75% success:

1. If I set my browser to UTF-8.

and

2. When composing my mail , if I set the message character set to  
ISO-1022-JP

then the received mail is fine in Japanese in all the POP3 clients  
I've tested.

Also, if the recipient replies, the received email appears fine in  
Horde's webmail Inbox. And subsequently downloading the email with my  
POP3 client is ok too.

The part that is still failing is that when viewing the email I sent  
in Horde's Sent folder, the title/subject of the mail is corrupted.  
The body of the mail is visible still in UTF-8, but I cannot read the  
sent email's subject.

Can somebody suggest how I might fix this, or other best practices  
for sending Japanese webmail in Horde?

Thanks,
