Byte Order Mark - Representations of Byte Order Marks By Encoding

Representations of Byte Order Marks By Encoding

This table illustrates how BOMs are represented as octet sequences and how they appear expressed in another encoding (here the legacy ISO-8859-1):

Famous quotes containing the words representations of, order and/or marks:

    “Dreams are distorted representations of desire. So are dream- analyses.”
    —Mason Cooley (b. 1927)

    “An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
    —Henri Bergson (1859–1941)

    “[Children] do not yet lie to themselves and therefore have not entered upon that important tacit agreement which marks admission into the adult world, to wit, that I will respect your lies if you will agree to let mine alone. That unwritten contract is one of the clear dividing lines between the world of childhood and the world of adulthood.”
    —Leontine Young (20th century)
