Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site. Why active installs don’t tell the whole story →

Overview
About this plugin
Features
It takes the following steps for getting cleaner and safe to use filenames
Removes or replace special/international characters that can make your filenames not compliant with servers that don’t have support for international locales and filenames, or third-party services. (e.g. ‘España.png’ will become ‘Espana.png’, ‘prüfen’ will become ‘prufen’).
Replaces any ‘+’ in the filename with ‘-‘ (e.g. ‘A+nice+picture.png’ will become ‘A-nice-picture.png’).
Replaces any ‘.’ character before the one used for file extension with ‘-‘(e.g. ‘A.nice.picture.png’ will become ‘A-nice-picture.png’).
After running all character replacement filters, a filter is applied to ensure that the filename only contains letters, numbers, underscores, dashes, and dots. Any other character will be removed from the filename.
And finally all letters in the filename are set to lowercase to prevent issues with case insensitive systems.
This reduces problems with some servers, services, plugins… That may have problems handling filenames with special or international characters.
The plugin does its job during file upload process, so it’ll change only filenames for files being uploaded after plugin activation.
