This paper proposes a novel hash function construction based on cascade chaos. Firstly, the L-length original message is divided into a number of blocks according to every character, which are transformed into corresponding ASCII values. Then the ASCII values are normalized into the interval of (0, 1), which compose a big array with the L-length. Regarding the first normalized ASCII value with ...

Unicode is an industry standard allowing computers to consistently represent and manipulate text expressed in most of the worlds writing systems. It is widely used in multilingual NLP (natural language processing) projects. On the other hand, there are some NLP projects still only dealing with ASCII characters. This paper describes methods of utilizing lexical tools to convert Unicode character...

Most existing computer systems which can handle a text file of arbitrarily mixed Chinese and ASCII characters use 8-bit codes. To exchange such text files through electronic mail on ASCII computer systems, it is necessary to encode them in a 7-bit format. A generic binary to ASCII encoder is not sufficient, because there is currently no universal standard for such 8-bit codes. For example, CCDO...

Because of the convenience of a text-based format 3D content is often published in form of a gzipped file that contains an ASCII description of the scene graph. While compressed image, audio, and video data is kept in separate binary files, polygon meshes and interpolators are usually included uncompressed into the ASCII description, as there is no widely-accepted standard for such data. In thi...

This paper describes a font independent Gurmukhi-to-Shahmukhi transliteration system. Even though Unicode is gaining popularity, but still there is lot of material in Punjabi, which is available in ASCII based fonts. A problem with ASCII fonts for Punjabi is there is no standardisation of mapping of Punjabi characters and a Gurmukhi character may be internally mapped to different keys in differ...

STD 11, RFC 822, defines a message representation protocol specifying considerable detail about US-ASCII message headers, and leaves the message content, or message body, as flat US-ASCII text. This set of documents, collectively called the Multipurpose Internet Mail Extensions, or MIME, redefines the format of messages to allow for (1) textual message bodies in character sets other than US-ASC...

(IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months. Internet-Drafts may be updated, replaced, or obsoleted by other documents at any time. It is not appropriate to use Internet-Drafts as reference material or to cite them other than as a "working draft" ...
