**Example 2**
Working with zod validation, zod resolver, react-hook-form and shadcn components

```javascript
import { useForm } from "react-hook-form";
import { z } from "zod";
import { zodResolver } from "@hookform/resolvers/zod";
import { PreetiToUnicodeInput } from "preeti-to-unicode-input";
// Import Shadcn form components
import {
  Form,
  FormField,
  FormItem,
  FormControl,
  FormLabel,
  FormMessage,
} from "./components/ui/form";
import { Input } from "./components/ui/input";

// Define Zod schema for validation
const formSchema = z.object({
  normalInput: z
    .string()
    .min(4, { message: "Input must be at least 4 character" }),
  preetiInput: z
    .string()
    .min(3, { message: "Input must be at least 3 characters" })
    .max(50, { message: "Input must be less than 50 characters" }),
});

const MyForm = () => {
  // Initialize react-hook-form with Zod resolver
  const form = useForm({
    resolver: zodResolver(formSchema),
    defaultValues: {
      normalInput: "",
      preetiInput: "", // Default form value for the input
    },
  });

  const onSubmit = (data: any) => {
    console.log("Form Data:", data); // Log submitted form data
  };

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(onSubmit)}>
        <FormField
          name="normalInput"
          control={form.control}
          render={({ field }) => (

              <FormControl>
                <Input placeholder="shadcn" {...field} />
              </FormControl>
              <FormMessage />
            </FormItem>
          )}
        />

        <FormField
          name="preetiInput"
          render={({ field }) => (
            <FormItem>

                      value={field.value}
                      onChange={(event) => field.onChange(event.target.value)}
