In UTF-8 o-umlaut should be encoded as 0xC3 0xB6, i.e. CHR$(195) plus
CHR$(182) so it sounds like your message has reached her OK, but is perhaps
getting double encoded before it is sent back.

You need to check the headers for the Content-Type, both the message you
sent to her, and the messages you receive back.  It said:

Content-Type: text/plain; charset=us-ascii

for the message you sent to this list.  I don't know whether Messenger
modifies the "charset" value if you include umlauts in the message.  If it
doesn't, that could contribute to the problem because a message with that
header should be confined to ASCII.

Also check what the header says for messages she sends to you.  If it is not
charset=utf-8 or something like that, it could explain why it is going wrong,
though I get the impression that anything she writes to you comes through OK,
it's just when she quotes your messages.  But you were not explicit about
whether she is using umlauts.
