Issue : Some Files and Folder names show garbled when uploaded to the dataroom.
Reason : Most zip programs (including the default compression application in windows) have limitations when creating zip files with Japanese/Chinese characters. Japanese (same as Chinese) is not in unicode UTF8, which is the universal coding.
Solution : Use 7Zip and set the parameter to "cu=on" to compress the files/folders that have Chinese/Japanese text. The parameter is the only change that needs to be done when compressing.
