+/**
+ * iconv implementation in pure PHP, UTF-8 centric.
+ *
+ * Implemented:
+ * - iconv              - Convert string to requested character encoding
+ * - iconv_mime_decode  - Decodes a MIME header field
+ * - iconv_mime_decode_headers - Decodes multiple MIME header fields at once
+ * - iconv_get_encoding - Retrieve internal configuration variables of iconv extension
+ * - iconv_set_encoding - Set current setting for character encoding conversion
+ * - iconv_mime_encode  - Composes a MIME header field
+ * - iconv_strlen       - Returns the character count of string
+ * - iconv_strpos       - Finds position of first occurrence of a needle within a haystack
+ * - iconv_strrpos      - Finds the last occurrence of a needle within a haystack
+ * - iconv_substr       - Cut out part of a string
+ *
+ * Charsets available for conversion are defined by files
+ * in the charset/ directory and by Iconv::$alias below.
+ * You're welcome to send back any addition you make.

+Symfony Polyfill / Php70
+========================
+
+This component provides features unavailable in releases prior to PHP 7.0:
+
+- [`intdiv`](https://php.net/intdiv)
+- [`preg_replace_callback_array`](https://php.net/preg_replace_callback_array)
+- [`error_clear_last`](https://php.net/error_clear_last)
+- `random_bytes` and `random_int` (from [paragonie/random_compat](https://github.com/paragonie/random_compat))
+- [`*Error` throwable classes](https://php.net/Error)
+- [`PHP_INT_MIN`](https://php.net/reserved.constants#constant.php-int-min)
+- `SessionUpdateTimestampHandlerInterface`
+
+More information can be found in the
+[main Polyfill README](https://github.com/symfony/polyfill/blob/master/README.md).
+
+Compatibility notes
+===================
+
+To write portable code between PHP5 and PHP7, some care must be taken:
+- `\*Error` exceptions must be caught before `\Exception`;
+- after calling `error_clear_last()`, the result of `$e = error_get_last()` must be
+  verified using `isset($e['message'][0])` instead of `null !== $e`.
