I searched and I did not see this reported, so I figured I would go ahead and file it. According to the W3C validator, links created using Upload are not HTML5 when files have spaces in their names. The validator throws the following exception: "Whitespace in path component. Use %20 in place of spaces."...."Syntax of IRI reference:
Any URL. For example: /hello, #canvas, or http://example.org/. Characters should be represented in NFC and spaces should be escaped as %20."
If you would like to check it out, go ahead and try this validating this page: http://www.croomsalumni.com/about using this validation service http://validator.w3.org/ (just remember to change the DocType to HTML5).
If I am correct, this should be pretty easy to fix, a simple replace function type of deal.
