Korean characters
The modern Korean writing system is called Hangul and officially used in North and South Korea. In
addition, Hanja is used which refers to the characters borrowed from Chinese.
Arabic alphabet
This script is used for writing several languages in Asia (e.g. Middle East, Pakistan,) and Africa (e.g.
Arabic and Urdu). It is written from right to left in a cursive style and includes 28 letters.
Unicode
Unicode is a standard for the consistent representation and use of characters found in the writing
systems of the world. It war not easy to adapt languages to computers, partly due to the large number
of characters of some languages. It is possible to encode one English character with just one byte
because written English only needs a small number of characters. This does not apply to languages
like Japanese, Chinese or Korean which have more than 256 characters and therefore require double
byte or multi-byte encoding. Several encoding methods are used and Unicode seems to be the most
universal method. It obviously encodes into all languages in the world.
For example the Han unification, contracted to Unihan, is an approach by Unicode and the Universal
Character Set (according to ISO 10646) to map several character sets of the Chinese, Japanese and
Korean languages in a single set of unified characters.
Arabic characters can be encoded by Unicode from Version 5.0 or higher (several character sets and
ISO 8859-6).
ISO 10646 specifies the Universal Multiple Octet Coded Character Set. It is used for the
representation, interchange, processing, storage and input of the written form of the languages in the
world as well as for additional symbols.
The Unicode standard versions 4...6 all comply with ISO 10646.
Pictogram
This is a graphical symbol, also called a pictograph, representing a concept, object, event or an
activity by illustration. Pictograms have been used for many thousand years. They are still important in
the event of language barriers and illiteracy in the modern world and are used as pictorial signs,
representational signs, instructions or statistical diagrams. Due to their graphical nature they are used
in different areas of life. To indicate, for example, to toilets and airports a standard set of pictograms is
defined in the standard ISO 7001 "Graphical Symbols - Public Information Symbols".
A pictogram has been developed into a functional visual language for people with cognitive problems.
Each image represents a word or concept. It comprises two elements, drawn images and text. The
symbols are mostly white on a black square.
