Unicode "smartphone emojis" break Preview
« on: September 13, 2019, 12:33:55 PM »
Tested with this 2.0.15 right here, 2.1rc2, and the Github HEAD of ~2019-09-01.

Entering a Unicode smiley like "🤔" breaks the Preview function, the preview box is just empty and the following error is displayed across all versions I tested:

The following error or errors occurred while posting this message:
The message body was left empty.

In 2.1, the very first rendering actually works, but if you preview again, it is empty.


Once you delete the emoji from your (original or quoted) text, Preview works again.


The problem seems to be caused by characters from (at least) the following Unicode blocks:

But not from these:

So you're seeing a correct preview and no error message? Only the first time you hit Preview, or does it work every time? (I see the error message every time; the first time I hit Preview, there's a preview, but not when I press Preview again.)

I'm on postgres btw, are you too?
