I'm having problems with some messages that use wide glyphs, especially mail from Ebay (even though I have chosen plain text mail).
The indentation following these messages is messed up. Here's a screenshot: http://www.r0t.uk/sshots/shot-5880465154.png rxvt-unicode identifies the delivery van as 1f69a in Symbola font and the tick as 2705 also in Symbola. I get the same problem when Noto Emoji is used. The same thing also happens in xfce4-terminal, which is a VTE based term and they are usually really good with wide fonts. My rxvt-unicode is patched with the latest wide glyph patches etc. I don't get this problem in vim at all. The indentation is correct there. I've looked on the net to see if there are any wide glyph patches for mutt, but came up empty.
