HTML messages with windows-1252 encoding are displayer incorrectly

I receive messages sent from outlook on windows. These messages are in French and contain special characters like "é" that are not displayed correctly (�). They contain both a text/plain and a text/html part.

Here is what they look like:

``` x-ms-exchange-generated-message-source: Mailbox Rules Agent Content-Type: multipart/alternative; boundary="_000_57bba51dacf74c928778457599539435CSIHMS05hdscetsi_" MIME-Version: 1.0

--_000_57bba51dacf74c928778457599539435CSIHMS05hdscetsi_ Content-Type: text/plain; charset="windows-1256" Content-Transfer-Encoding: quoted-printable

CONFIDENTIAL with =E9

--_000_57bba51dacf74c928778457599539435CSIHMS05hdscetsi_ Content-Type: text/html; charset="windows-1256" Content-Transfer-Encoding: quoted-printable

<meta http-equiv='3D"Content-Type"' content='3D"text/html;' charset="3Dwindows-1="> <meta name='3D"Generator"' content='3D"Microsoft' word="" 15="" (filtered=""> <style><!-- REMOVED FOR CONCISENESS --></style> CONFIDENTIAL with =E9

--_000_57bba51dacf74c928778457599539435CSIHMS05hdscetsi_-- ```

If I select View > Text Encoding > Western, it works in both HTML and plain text. However, there is no way to make this setting persist. I set the default encoding of incoming emails to Windows-1252 but View > Text Encoding still shows Unicode when I re-open the message.

the issue is windows-1252 is not a registered charset in Thunderbird.

See https://www.w3schools.com/charsets/ref_html_ansi.asp for some background. Thunderbird uses the ISO standard not the Microsoft modified version.

Hi Matt, Thank you a lot for your answer, I really appreciate it! I am not sure about windows-1252, but Thunderbird can definitely read this encoding. Furthermore, I have reasons to think that "Western" is the other name of windows-1252: when I reply to an email that I'm reading with windows-1252, here is what I see bottom right of the screen https://i.imgur.com/KX9tClF.png
