Base64 is often used to embed binary data in an XML file, using a syntax similar to <data encoding="base64">…</data> e.g. favicons in Firefox's exported bookmarks.html. Base64 is used to encode binary files such as images within scripts, to avoid depending on external files. Base64 can be used to embed PDF files in HTML pages. [15]
In this example, the image data is encoded with utf8 and hence the image data can broken into multiple lines for easy reading. Single quote has to be used in the SVG data as double quote is used for encapsulating the image source. A favicon can also be made with utf8 encoding and SVG data which has to appear in the 'head' section of the HTML:
The ASCII text-encoding standard uses 7 bits to encode characters. With this it is possible to encode 128 (i.e. 2 7) unique values (0–127) to represent the alphabetic, numeric, and punctuation characters commonly used in English, plus a selection of Control characters which do not represent printable characters.
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
Web pages authored using HyperText Markup Language may contain multilingual text represented with the Unicode universal character set.Key to the relationship between Unicode and HTML is the relationship between the "document character set", which defines the set of characters that may be present in an HTML document and assigns numbers to them, and the "external character encoding", or "charset ...
Microsoft Office Word Add-in For MediaWiki: Converts Word documents to wiki formatting. Doesn't do images. This may not work on newer versions of Word. Excel2Wiki tool for converting Excel tables to wiki tables. Transferring a single wiki page in MediaWiki to Word is easy, just save the desired webpage and then open the page in Microsoft Word.
encoded text is the Q-encoded or base64-encoded text. An encoded-word may not be more than 75 characters long, including charset , encoding , encoded text , and delimiters. If it is desirable to encode more text than will fit in an encoded-word of 75 characters, multiple encoded-word s (separated by CRLF SPACE) may be used.
The authorization method and a space character (e.g. "Basic ") is then prepended to the encoded string. For example, if the browser uses Aladdin as the username and open sesame as the password, then the field's value is the Base64 encoding of Aladdin:open sesame, or QWxhZGRpbjpvcGVuIHNlc2FtZQ==. Then the Authorization header field will appear as:
