HTML Decimal Character Rendering

HTML Decimal Character Rendering

A numeric character reference in HTML refers to a character by its Universal Character Set/Unicode code point, and uses the format

&#nnnn;

or

&#xhhhh;

where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form. The x must be lowercase in XML documents. The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style.

Not all web browsers or email clients used by receivers of HTML documents, or text editors used by authors of HTML documents, will be able to render all HTML characters. Most modern software is able to display most or all of the characters for the user's language, and will draw a box or other clear indicator for characters they cannot render.

For codes from 0 to 127, the original 7-bit ASCII standard set, most of these characters can be used without a character reference. Codes from 160 to 255 can all be created using character entity names. Only a few higher-numbered codes can be created using entity names, but all can be created by decimal number character reference.

Famous quotes containing the words rendering, character and/or decimal:

    By rendering the labor of one, the property of the other, they cherish pride, luxury, and vanity on one side; on the other, vice and servility, or hatred and revolt.
    James Madison (1751–1836)

    Progressive art can assist people to learn not only about the objective forces at work in the society in which they live, but also about the intensely social character of their interior lives. Ultimately, it can propel people toward social emancipation.
    Angela Davis (b. 1944)

    It makes little sense to spend a month teaching decimal fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children’s developing interests and abilities.
    David Elkind (20th century)
