Function `std.uni.byCodePoint`

Lazily transform a range of Graphemes to a range of code points.


						
				auto byCodePoint(Range)
				(
				

				  Range range
				

				)
				

				if (isInputRange!Range && is(immutable(ElementType!Range) == immutable(Grapheme)));
				

				

				auto byCodePoint(Range)
				(
				

				  Range range
				

				)
				

				if (isInputRange!Range && is(immutable(ElementType!Range) == immutable(dchar)));

Useful for converting the result to a string after doing operations on graphemes.

If passed in a range of code points, returns a range with equivalent capabilities.

Example

import std.array : array;
import std.conv : text;
import std.range : retro;

string s = "noe\u0308l"; // noël

// reverse it and convert the result to a string
string reverse = s.byGrapheme
    .array
    .retro
    .byCodePoint
    .text;

assert(reverse == "le\u0308on"); // lëon
