I'm just catching up, and am not working on Wine yet. So just fyi recently there was a patchset at WineHQ for Unicode 10:
https://www.winehq.org/pipermail/wine-patches/2017-July/163321.html https://www.winehq.org/pipermail/wine-patches/2017-July/163322.html That one got rejected, but I assume it at least made Wine build again. Alternatively, I wonder if it is acceptable to temporarily embed the Unicode 9 files in our source packages. (I'm quite sure that WineHQ will update to 10 soon, definitely in time for buster.)
