I am building a Wordpress site that is going to be multilingual (using WPML) and it will host a ton of resources in multiple languages - from Chinese to Russian to English, etc. We wanted to upload the files using the native languages filename and I was going to add a filter to
sanitize_file_name to accomplish this. After some reading, I cannot find a good explanation of why this may not be a good idea.
My question is, why would this not be a good idea? Should I avoid this? What implications would it have if I allowed all characters to be used?
Thanks for your help!
