Added JSON_UNESCAPED_UNICODE flag to json_encode

It helps to dramatically reduce the generated JavaScript file size

In my testing, I was able to reduce file size from 170kb to 90kb because I had lots of escaped Cyrillic characters.

It's a tiny change, can we just accept it?

What happens if someone's environment is not set to accept files encoded in non-ascii?

It can be as a configuration option "unescape_unicode" that defaults to false

[SerhiiCho]

It would look like this in the config file:

<?php

return [
    /*
     * Determines whether to use the JSON_UNESCAPED_UNICODE flag when encoding
     * translation files to JSON.  
     * 
     * Setting this to true will prevent Unicode characters from being escaped 
     * (e.g., "你好" instead of "\u4f60\u597d"), which can reduce file size 
     * and improve readability.  
     * 
     * Set to false to escape Unicode characters for compatibility.
     */
    'unescape_unicode' => false,

    /*
     * Set the names of files you want to add to generated javascript.
     * Otherwise all the files will be included.
     *
     * 'messages' => [
     *     'validation',
     *     'forum/thread',
     * ],
     */
    'messages' => [

    ],

    /*
     * The default path to use for the generated javascript.
     */
    'path' => public_path('messages.js'),
];

I can make a PR after I get some feedback. This current PR is also mine from the previous company's account nalognl
