Super Unicode Editor (SUE) is a program that is somewhere between a text editor and a hex editor. In it's simplest form, it can edit plain text like Notepad with the 'Text' edit format, or it can edit binary files byte-by-byte like any hex editor with the 'Binary' edit format. Beyond that, it can also edit files in UTF-8, UTF-16, and UTF-32 formats with a smart display of Unicode codepoints. Files can be read in one format, while edited in another, with multiple different views of the same file open at once.
