Seems like this might be a dupe of #695?

[TheOneric]

Yep, the — (U+2014) all use @-fontnames, so this is a duplicate of #695.

[rcombs]

Actually, I suspect #695 is just an outdated libass; this is instead a dupe of the related-but-distinct waddou/libass#95, so I'll reopen to have a GHI for that within our repo.

It does. Thankfully, this font was easy to find (方正报宋_GBK aka FZBaoSong-Z04, or at least that’s what the one I found claims to be). If in doubt, please include the sample’s fonts next time; thanks!
