Aurigma Upload Suite 8.0.67
UploadSettings..::.UrlEncodeFilenames Property HTML5/Flash Uploader ASP.NET
Specifies whether to apply URL encoding to filenames uploaded by the uploader.
Assembly: Aurigma.ImageUploaderFlash (in Aurigma.ImageUploaderFlash.dll)
This property may be helpful if your server incorrectly accepts files with non-ASCII names. In this case, just set it to true and use URL decoding when reading those file names from the request.
When this property is true, the uploader sends the FilenamesUrlEncoded POST field set to true. This way you can add the code to your server side script which determines if the filenames require pre-processing (URL decoding).
