    import std.format : format;

    string hex = format("%(%2x%)", "Hello World");

    import std.stdio : writeln;
    writeln(hex);

A bit of explanation: %(  %) is a range formatting specifier, and basically means "format each element of the range with the format specifier between these two symbols". In other words, it's the equivalent of "Hello World".map!(c => format("%2x", c)).joiner.
