If you create a custom field “file†and set it to only allow images and you upload an image with characters other then browser compatible A-Z, a-z, 0-9, -_ etc. the file popup manager doesn’t clean em.
So if I upload the image “Abcö.jpg†the “ö†doesn’t get renamed to “o†or cleaned away completely. So when you then try to use the image on your site you get errors since the browser can’t use images with those characters.
