zip archive, fastest mode.
7zip; 41s; 182,426,378B; unicode filename OK in itself and WinRAR, messed up in compressed folders.
winrar; 36s; 185,347,324B; unicode filename OK in itself, converted to #Unnnn code in 7zip and compressed folders.
izarc; ; 280,268,260B; unicode filename OK in itself, messed up in compressed folders, WinRAR and 7zip, opens archive very slowly (default flat mode).
peazip: uses 7zip for zip, opens slowly because of default flat mode.
Conclusion: Winrar compresses into zip archive with highest speed but a bit larger size, and it handles unicode filename with best compatibility.
