filenames containing plus sign +

[spressi]

Hi Lisa,
I found an interesting bug today. If a file contains a plus sign in its filename during upload, the file content is depicted as empty in Webmorph (the preview also does not work). Also, after downloading it from Webmorph and opening it locally, the problem persists.
It probably has to do with plus signs in the browser being used as special characters. Therefore, when parsing file names during upload, plus signs should probably be replaced with underscores (as is already performed for whitespaces).
Best regards,
Mario
