There are potential problems for both static and dynamic documents if they are not read from a server for example, if they are saved to a In-document declaration may cause the document to become unreadable. This is a very bad situation, since the higher precedence of the HTTP information versus the Rely on the server default, and that default is changed. Server settings may get out of synchronization with the document for one reason or another. It may be difficult for content authors to change the encoding information for static files on the server – especially when dealing with an ISP.Īuthors will need knowledge of and access to the server settings. On the other hand, there are a number of potential disadvantages:
If it is, and it is converting content to non-UTF-8 encodings, it runs a high risk of loss of data, and so is not good practice. It is not clear that this transcoding is much used nowadays. convert to a different encoding) could take advantage of this to change the encoding of a document before sending it on to small devices that only recognize a fewĮncodings.
The HTTP header information has the highest priority when it conflicts with in-document declarations other than the byte-order mark. One advantage of using the HTTP header is that user agents can find the character encoding information sooner when it is sent in the HTTP header. Use character encoding declarations in HTTP headers if it makes sense, and if you are able, for any type of content, but in conjunction with an in-document declaration.Ĭontent authors should always ensure that HTTP declarations are consistent with the in-document declarations. Should I declare the encoding in the HTTP header?

You could skip the meta encoding declaration if you have a BOM, but we recommend that you keep it, since it helps people looking at the source code to ascertain what the encoding of the page is. It has a higher precedence than any other declaration, including the HTTP header. If you have a UTF-8 byte-order mark (BOM) at the start of your file then recent browser versions other than Internet Explorer 10 or 11 will use that to determine that the encoding of your page is UTF-8. You can detect any encodings sent by the HTTP header using the Internationalization Checker. If it is, the meta element must be set to declare the same encoding. Note however that, since the HTTP header has a higher precedence than the in-document meta declarations, content authors should always take into account whether the character encoding is already declared in the HTTP header.
If you have access to the server settings, you should also consider whether it makes sense to use the HTTP header. (Remember that this means you also need to save your content as UTF-8.) See what you should consider if you really cannot use UTF-8. You should always use the UTF-8 character encoding. It also doesn't matter whether you type UTF-8 or utf-8. It doesn't matter which you use, but it's easier to type the first one. The declaration should fit completely within the first 1024 bytes at the start of the file, so it's best to put it immediately after the opening head tag. Quick answerĪlways declare the encoding of your document using a meta element with a charset attribute, or using the http-equiv and content attributes (called a pragma directive). For information about declaring encodings for CSS style sheets, see CSS character encoding declarations. If you need to better understand what characters and character encodings are, see the article Character encodings for beginners.

This article describes how to do this for an HTML file. A character encoding declaration is also needed to process non-ASCII characters entered by the user in forms, in URLs generated by scripts, and so forth. This is not just an issue of human readability, increasingly machines need to understand your data too. If you don't, you risk that characters in your content are incorrectly interpreted. You should always specify the encoding used for an HTML or XML page. How should I declare the encoding of my HTML file?
