I can see those working fine on this mailing list both through my mail
client and through both of the online mailing list browsers ( https://www.winehq.org/pipermail/wine-devel/ && http://news.gmane.org/gmane.comp.emulators.wine.devel ) So, are You sure there is an actual problem? Probably the encoding of the mail sent by wine-devel-digest is not formatted as Unicode. It doesn't problem of server, but the mail. All chinese characters are viewed as ??????? in my gmail. It is a SMTP's problem,isn't it?
