Utilizing jQuery to convert letter input values into English: a step-by-step guide

I am developing a basic web application using Jquery. In this application, I aim to restrict user input language. For instance, if a user enters the Russian letter б in the input field, I want to automatically convert it to an English character. Below is a simplified example of what I am attempting:

$("#name").keyup(function() {
    var charsObject = {
        'а': 'a',
        'б': 'b',
        'г': 'g',
    };
    console.log($(this).val())
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" id="name">

Here is a method to sanitize input in real-time, whether you are typing or pasting text using the right mouse button:

$("#name").on("input", function() {
  var carr='бb,гg'.split(',').map(e=>e.split(''));
  let s=$(this).val();
  carr.forEach(([k,v])=>s=s.replaceAll(k,v));
  $(this).val(s)
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" id="name">

In this updated version, I have replaced the charsObject with an array of arrays (carr) for a more direct processing in the input event handler.
