Function `std.uni.normalize`

Returns input string normalized to the chosen form. Form C is used by default.


						
				inout(C)[] normalize(NormalizationForm norm = NFC, C)
				(
				

				  scope return inout(C)[] input
				

				);

For more information on normalization forms see the normalization section.

Note

In cases where the string in question is already normalized, it is returned unmodified and no memory allocation happens.

Example

// any encoding works
wstring greet = "Hello world";
assert(normalize(greet) is greet); // the same exact slice

// An example of a character with all 4 forms being different:
// Greek upsilon with acute and hook symbol (code point 0x03D3)
writeln(normalize!NFC("ϓ")); // "\u03D3"
writeln(normalize!NFD("ϓ")); // "\u03D2\u0301"
writeln(normalize!NFKC("ϓ")); // "\u038E"
writeln(normalize!NFKD("ϓ")); // "\u03A5\u0301"
