If your filenames contain two near-identical Unicode characters, rclone will normalize these, making them identical. This flag gives you the ability to keep them unique. This might create unintended side effects, such as duplicating files that contain certain Unicode characters, when downloading them from certain cloud providers to a macOS filesystem. Fixes #4228
