I also note that I cannot open the file directly from URL because it is in the archive, so I need archive manager to unpack it. So I cannot use 'open..' dialogue to open file fom the network. Only after I opened the file with doule-clicking (with incorrect encoding), then close it and then use 'open..' dialogue which opens the same file probably from cache, but in this case the encoding chooser though exists, does not work and the file is opened in default encoding in any case.
