So this is a case of curiosity more than anything.
I am in the process up loading images for a very large number of collegiate products from a certain vendor. Part of this process includes grabbing the style # and searching for it in the folder that contains all the images. For some reason, this doesn't work when I search for any of the products that end in "R". If I delete the R, the image will show up - and if I replace it with a lower case "r", the product will show up. Using an upper case "R" causes the search to fail again.
Since I know it is happening it isn't really a problem for me, but it is weird. I don't know much about how Windows Explorer handles fonts/characters, so I could begin to speculate what is causing this.
Incidentally, I get the same result if I try to search through the pop-up dialog when I go to upload the image, or if I actually navigate to the folder within Explorer. Either way, the filenames that end in "R" can't be found.
