After I refused to use Microsoft Windows XP in favor of Mac OS X, I had a single request to Uncle Bill: make UTF-8 encoding in your OS, as in all other systems, and I have no complaints about you will remain! For nothing gives people a better understanding of each other on the network, as the unity of the encoding.
PS: Of course, little things for tagging songs, and, for example, encodings on ftp-servers, will be a plus for everyone. The rest of the wine does not interest me very much.
