**Special Characters**

The HCD Content Retrieval Interface supports multi-byte languages, allowing the inclusion of special characters ranging from simple accents, such as umlauts, to more complex character sets. This ensures compatibility with a wide range of languages and symbols.

Suppliers can reference the **Unicode Code Chart for Symbols and Special Punctuation** to identify the requirements and encoding for each character. This resource helps ensure that all special characters are handled correctly in the content [http://www.unicode.org/charts/symbols.html](http://www.unicode.org/charts/symbols.html).
