Example text

This perspective highlights the essentially intellectual aspect of the document domain: a res (an ‘object’) takes on the status of a document only because the person, who aims at exploiting it in that meaning, is provided with an intellectual code for understanding it [9]. As a consequence, it seems straightforward to conclude that the document, juridically intended, does not exist in nature, but exists only if the suitable circumstances hold to ascribe this particular meaning to an object [3].

UTF-8 is compliant to ISO/IEC 8859-1 and fully backward compatible to ASCII (and, additionally, non-ASCII UTF-8 characters are just ignored by legacy ASCIIbased programs). Indeed, due to rule 1, UTF-8 represents values 0–127 (0016 –7F16 ) using a single byte with the leftmost bit at 0, which is exactly the same representation as in ASCII (and hence an ASCII file and its UTF-8 counterpart are identical). As to ISO/IEC 8859-1, since it fully exploits 8 bits, it goes from 0 to 255 (0016 – FF16 ). Its lower 128 characters are just as ASCII, and fall, as said, in the 1-byte 4 As a trivial example of how tricky UTF-16 can be: usual C string handling cannot be applied because it would consider as string terminators the many 00000000 byte configurations in UTF-16 codes.

1 Compression Techniques 19 The repetitions are searched in a limited buffer consisting of the last N kB (where N ∈ {2, 4, 32}), whence it is called a sliding window technique. Implementations may adopt different strategies to distinguish length–distance pairs from literals and to output the encoded data. The original version exploits triples (length, distance, literal), where • length–distance refers to the longest match found in the buffer, and • literal is the character following the match (length = 0 if two consecutive characters can only be encoded as literals).
