Change subject directly when the selected string occurs only once

[Thomas-D-C]

Background

I just tried it by myself, so is it also known/reported that the text you select in the subject line is then not actually being replaced in the subject line, but pasted into the body?

Yes, that is also a known issue, see rugk/awesome-emoji-picker#49 (comment). In short, I filed bug 1641575, but they marked it as WONTFIX.

I have some changes locally that would copy it to the clipboard in this case as a workaround. However, we would likely need to also display a notification to the user so they would know to then hit Ctrl + V

For the Unicode font conversion feature of this add-on, one could use setComposeDetails/getComposeDetails as long as the selected string only occurs once in the subject.

Thanks to your new "sentence case" feature, which allows you to select the entire subject and then apply it, I realized that it is rather rare to have multiple occurrences of the text I want to transform in the subject.

Proposed solution

I think it would be a good idea to save time, to use setComposeDetails when the selected string occurs only once in the subject.

If it occurs more than once, it would be ambiguous as to which one to replace.

I suggest you keep the current workaround for that case. We can see later if it's possible to improve it further.
