Formatting the subject line
While looking over my junk folder, I notice that many messages have a variety of interesting formats, rather than plain text. But Thunderbird doesn't seem to support any formatting of the subject line. I think the ideal way to do it would be to enable HTML formatting of the subject line, but a search didn't turn up any information as to how to do this. So, is it at all possible to format the Subject line?

Subject lines can be crafted using unicode fonts, but Thunderbird does not have any sort of generator for that and probably will not for some time to come as the actual body text is HTML formatted not using the higher level Unicode font features
Currently you are limited to tools like http://qaz.wtf/u/convert.cgi?text=Email+rocks Which will apply some styles to the text.
and https://tools.bluestatedigital.com/kb/subject-line-assistant which encodes the emoji images in Unicode fonts into the subject line.
Or https://yaytext.com/ which appear to offer a combination of the other two sites.
Basically you been to use a considered approach as many people appear to treat anything with an emoticon or formatted text in the subject as spam. They read nothing just get rid of it because of the formatting as until now about the only emails with formatting are spam.
