The Symfony Polyfill / Iconv Component

This component provides a native PHP implementation of the iconv_* functions to users who run PHP versions without the iconv extension.

Installation

$ composer require symfony/polyfill-iconv

注釈

If you install this component outside of a Symfony application, you must require the vendor/autoload.php file in your code to enable the class autoloading mechanism provided by Composer. Read this article for more details.
