Bug#860445: libvte9: U+1F3DB CLASSICAL BUILDING incorrectly rendered as a singlewidth character

[Alexis Hunt]

Package: libvte9
Version: 1:0.28.2-5+b2
Severity: normal

Dear Maintainer,

I noticed recently that U+1F3DB CLASSICAL BUILDING is incorrectly being rendered
as a singlewidth character when it, like most (all?) emoji, is actually
doublewidth. The result is that it overlaps with the subsequent character. It
should be rendered as doublewidth.

I have reproduced this in Terminator and in rxvt-unicode.
