WinRAR 4.10 beta 4 更新項目: 1. Improved detection of UTF-8 encoding in file names in ZIP archives. WinRAR attempts to recognize Unicode names, even when UTF-8 flag is not present in ZIP archive headers. 2. Bugs fixed: a) If switch -t was set in RAR environment variable, WinRAR "View" command failed to open archived files; b) ""Autodetect" string" option in "Define volume sizes" dialog did not work; c) If "Split to volumes, size" in default compression profile was set to "Autodetect", "Delete" and "Add comment" commands refused to modify ZIP archives.
