BEA - Sanitize Filename

This plugin allows you to sanitize files on upload, which is pretty handy. It means all punctuation and accents from the filename of uploaded files will be removed. Features

• All accented letters will be converted to same letters without accent
• Special characters will be deleted
• Underscores will be replaced by hyphens

Warning For Mac Owners On MAC, you can also create an accented character with the combination of ` and the wanted letter. This has the effect to create a character with a special filename system encoding format which is not sanitized. An issue is already open about this. Who ?
