Basic use

Use the  New  command in the  File  menu to open a new window.

Type or paste in any text into the top box, labelled  Input , and press the  Tab  or  Enter  key.

The text  HFS+  will then appear on a red or green background.  Red  indicates that macOS running on an HFS+ file system will change that text during normalisation. The version of your text shown next to that gives the normalised form which will be used for file and folder names.

If the background is  green , then no change will take place with normalisation: both the original and normalised forms are identical.

The four boxes below that give the four different normalised forms, using hexadecimal numbers in UTF-8 format (Unicode). Macs with HFS+ use  NFD , but Linux uses  NFC , for example.

The bottom box gives a full summary, which you can  Save  as a text file using that command in the  File  menu.

You can open as many new windows as you want, and can copy and paste between them and other apps.
