And also optionally apply one of the normalization forms first. (NFC uses the composed code point wherever possible (à = 224), whereas NFD decomposes into parts (à = 97, 768); the K variants are for compatibility forms (NFKD decomposes the f-i ligature fi into f and i (and so does NFC, for that matter), plain NFD doesn't).) There's also a hexadecimal version of this tool, as well as a undo operation that can take the lists formed here and turn them back into strings.
