Markup Validation Service

I was not able to extract a character encoding labeling from any of the valid sources for such information. Without encoding information it is impossible to reliably validate the document. I'm falling back to the "UTF-8" encoding and will attempt to perform the validation, but this is likely to fail for all non-trivial documents.

The sources I tried to find encoding information include:

• The HTTP Content-Type field.
• The XML Declaration.
• The HTML "META" element.

And I even tried to autodetect it using the algorithm defined in Appendix F of the XML 1.0 Recommendation.

Since none of these sources yielded any usable information, I will not be able to reliably validate this document. Sorry. Please make sure you specify the character encoding in use.

Specifying a character encoding is normally done in the web server configuration file or administration program. The W3C I18N Activity has collected a few tips on how to do this in popular web server implementations.

IANA maintains the list of official names for character sets and the WDG has some information to help you correctly specify the character encoding.

To quickly check whether the document would validate after addressing the missing character encoding information, you can use the "Encoding" form control (accesskey "2") earlier in the page to force an encoding override to take effect. "iso-8859-1" (Western Europe and North America) and "utf-8" (Universal, but not commonly used in legacy documents) are common encodings if you are not sure what encoding to choose.
