 // A Form denotes a canonical representation of Unicode code points.
 // The Unicode-defined normalization and equivalence forms are:
 //
-//   NFC   Unicode Normalization Form C
-//   NFD   Unicode Normalization Form D
-//   NFKC  Unicode Normalization Form KC
-//   NFKD  Unicode Normalization Form KD
+//	NFC   Unicode Normalization Form C
+//	NFD   Unicode Normalization Form D
+//	NFKC  Unicode Normalization Form KC
+//	NFKD  Unicode Normalization Form KD
 //
 // For a Form f, this documentation uses the notation f(x) to mean
 // the bytes or string x converted to the given form.
 // A position n in x is called a boundary if conversion to the form can
 // proceed independently on both sides:
-//   f(x) == append(f(x[0:n]), f(x[n:])...)
+//
+//	f(x) == append(f(x[0:n]), f(x[n:])...)
