A Symfony component that provides a native PHP implementation of the iconv extension functions for environments where the extension is unavailable. It acts as a drop-in compatibility shim so code depending on iconv works across PHP setups.

Use cases

• use iconv functions when the PHP iconv extension is missing
• make a PHP library portable across hosts without iconv installed
• ensure consistent character encoding conversion behavior across environments
• add iconv compatibility to a legacy PHP application
• avoid hard dependency on PHP extensions in a composer package

When to choose

• your PHP code calls iconv functions and must run on hosts without the extension
• you maintain a library that should work on minimal PHP installations
• you want a drop-in, MIT-licensed shim maintained by the Symfony ecosystem

When to avoid

• the iconv extension is already installed and enabled on your target environments
• you need ob_iconv_handler, which this polyfill does not implement
• you need full-featured character encoding conversion beyond iconv's API
