import std.stdio;
import std.algorithm : canFind;
import std.uni : normalize;

void main()
{
    auto a = "á".normalize;
    auto b = "á".normalize;
    auto c = "\u200B".normalize;
    auto x = a ~ c ~ a;
    auto y = b ~ c ~ b;

    writeln(a.length); // 2
    writeln(b.length); // 2
    writeln(x.length); // 7
    writeln(y.length); // 7

    writeln(a == b); // true
    writeln("ááááááá".canFind("á".normalize)); // true
