+Charset
+=======
+
+.. versionadded:: 7.1
+
+    The ``Charset`` constraint was introduced in Symfony 7.1.
+
+Validates that a string is encoded in a given charset.
+
+==========  =====================================================================
+Applies to  :ref:`property or method <validation-property-target>`
+Class       :class:`Symfony\\Component\\Validator\\Constraints\\Charset`
+Validator   :class:`Symfony\\Component\\Validator\\Constraints\\CharsetValidator`
+==========  =====================================================================
+
+Basic Usage
+-----------
+
+If you wanted to ensure that the ``content`` property of an ``FileDTO``
+class uses UTF-8, you could do the following:
+
+.. configuration-block::
+
+    .. code-block:: php-attributes
+
+        // src/Entity/FileDTO.php
+        namespace App\Entity;
+
+        use Symfony\Component\Validator\Constraints as Assert;
+
+        class FileDTO
+        {
+            #[Assert\Charset('UTF-8')]
+            protected string $content;
+        }
+
+    .. code-block:: yaml
+
+        # config/validator/validation.yaml
+        App\Entity\FileDTO:
+            properties:
+                content:
+                    - Charset: 'UTF-8'
+
+    .. code-block:: xml
+
+        <!-- config/validator/validation.xml -->
+        <?xml version="1.0" encoding="UTF-8" ?>
+        <constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping"
+            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+            xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping https://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd">
+
+            <class name="App\Entity\FileDTO">
+                <property name="content">
+                    <constraint name="Charset">
+                        <option name="charset">UTF-8</option>
+                    </constraint>
+                </property>
+            </class>
+        </constraint-mapping>
+
+    .. code-block:: php
+
+        // src/Entity/FileDTO.php
+        namespace App\Entity;
+
+        use Symfony\Component\Validator\Constraints as Assert;
+        use Symfony\Component\Validator\Mapping\ClassMetadata;
+
+        class FileDTO
+        {
+            // ...
+
+            public static function loadValidatorMetadata(ClassMetadata $metadata): void
+            {
+                $metadata->addPropertyConstraint('content', new Assert\Charset('UTF-8'));
+            }
+        }
+

+
+``message``
+~~~~~~~~~~~
+
+**type**: ``string`` **default**: ``The detected encoding "{{ detected }}" does not match one of the accepted encoding: "{{ encodings }}".``
+
+This is the message that will be shown if the value does not match any of the
