OS: Windows 10 22H2
Zig: 0.12

	const std = @import("std");
	const c = @cImport({
	@cInclude("windows.h");
	});
	pub fn main() !void {
	const message = "Hello, World!";
	const title = "Zig MessageBox";
	// Buffer for UTF-16 strings
	var message_w: [100]u16 = undefined;
	var title_w: [100]u16 = undefined;
	// Convert UTF-8 string to UTF-16LE
	const message_len = std.unicode.utf8ToUtf16Le(&message_w, message) catch {
	std.log.err("Error converting message string", .{});
	return;
	};
	const title_len = std.unicode.utf8ToUtf16Le(&title_w, title) catch {
	std.log.err("Error converting title string", .{});
	return;
	};
	// Null-terminate the UTF-16 strings
	message_w[message_len] = 0;
	title_w[title_len] = 0;
	// Calling MessageBoxW
	_ = c.MessageBoxW(null, message_w[0..message_len :0], title_w[0..title_len :0], c.MB_OK);
	}
