20 Converts a string into canonical form, standardizing such issues as
21 whether a character with an accent is represented as a base character
22 and combining accent or as a single precomposed character.
23
24 The normalization mode is NFKC (ALL COMPOSE). It standardizes differ‐
25 ences that do not affect the text content, such as the above-mentioned
26 accent representation. It standardizes the "compatibility" characters
27 in Unicode, such as SUPERSCRIPT THREE to the standard forms (in this
28 case DIGIT THREE). Formatting information may be lost but for most text
29 operations such characters should be considered the same. It returns a
30 result with composed forms rather than a maximally decomposed form.
31
33 a newly allocated string, that is the NFKC normalized form of str.
