How to read a file with URL encoding in the file name

I have a workflow that needs to read files from a Subversion repository that is available via a URL.  Many of the files were created with the %20 URL encoding used to replace an ASCII space.  When I try to read these files I get a (404) Not Found error.  I assume that when the name is being resolved the system is replacing the %20 with a space.  The files that do not have the URL encoding process without any problems.

I am using a Read Files component with the File Path Type set to URL.  Does anyone have a suggestion for getting the system to read the %20 as valid characters in the file name?
