239066 - &# entities in HTML mails don't get converted in plain text mode

Status: RESOLVED DUPLICATE of bug 166521

(MailNews Core :: MIME, defect)

Description

[Robert Kaiser]

I'm getting some HTML mail newsletters in German that have all non-ASCII
characters encoded with &# unicode entities.
Those characters are not converted in "view as plain text" mode, so it's hard to
read those mails that way. I guess this might be quite easy to achieve though,
as those entities are even understood correctly by XML, XUL et al.

Finally, I got another message that shows this behaviour. I discovereed that it
has a really wrong text/plain part that might be the real cause of what I'm
seeing. We should try what happens if we have the HTML part only. If the
entities are not transformed there, we have a bug there, else it's just
INVALID, I guees.

Error at sending side. The plaintext part is invalid. "ö" means "ö" in
HTML, but just "ö" in plaintext. Workaround: Use Simple HTML mode.
