Incorrect rendering of ISO 8859-1 mail

Reported by John Cooper | October 24th, 2022 @ 04:58 PM

Build 5918.

A received message includes the line

Content-type: text/html; charset=iso-8859-1

and the following HTML:

However, the formatted text displays the name incorrectly.

By contrast, the same message is rendered in Apple Mail as expected.

It seems that MailMate is not correctly rendering ISO 8859-1 mail, at least when the encoding is specified in Content-Type.

    Pete Resnick points out that the content-type should be specified as UTF-8 and not ISO-8859-1, and that this is an error on the sender's point. However, MailMate could handle such a situation more gracefully, either by automatically correcting for the error (as Mail does) or by providing a Eudora-style character set menu to the user.

    If possible, forward me the problematic message using “Message > Forward as Attachment” and I might have time to look into if it's possible to make a workaround.

    • State changed from “new” to “fixcommitted”

    In the next update I've added a strategy where the specified charset is ignored if a number of non-7bit characters are used and the text is valid UTF-8. We'll see, but this should be a pretty safe assumption in general (due to how UTF-8 works). In any case, it won't affect the most common and hopefully some day one and only case (the use of UTF-8).
