An introduction to the complex text languages

The following characters are added to the basic set, in a way similar to the accented characters in Latin-based languages: In addition, two special characters Aleph Wasla and superscripted Aleph are sometimes used in language education and linguistics.

The Arabic alphabet is also the root from which several other alphabets, such as Farsi and Urdu, are derived. In addition to the characters of the Arabic alphabet, the Farsi and Urdu alphabets have a few more specific characters. Farsi adds four consonants to the Arabic alphabet, and Urdu adds eight.

Character Set Considerations The Arabic character set has the following characteristics: Written Arabic has no equivalent to capital letters. The same Arabic characters take on different shapes depending on their position in a text string and on the surrounding characters.

Arabic script is cursive. Most characters of a word are connected to each other, as in English handwriting.

Characters can be joined to form ligatures. A character can be represented with a vowel or diacritic mark written over or under it. Arabic characters have different lengths. As a result, wider characters are sometimes represented on some devices as two coded shapes.

Shapes of the Arabic Characters Arabic code pages can contain from one to four shapes for each character or ligature, depending on the implementation. The four possible shapes of an Arabic character are: Isolated The character is not linked to either the preceding or the following character. Final The character is linked to the preceding character but not to the following one.

Initial The character is linked to the following character but not to the preceding one. Middle The character is linked to both the preceding and following characters. The Arabic Character Ghayn in its Different Shapes In a text string, both the connection capabilities of a character and its neighbours, and its position in the word determine its actual presentation shape.

Numerals Used in Arabic In countries using Arabic script, the decimal system is in use. In addition to the "Arabic" digits used in the Western world, national digit shapes, known as Hindi shapes, are in use.

The equivalent of the Arabic digits 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 are: It remained relatively unchanged for about years until the end of the nineteenth century, when the birth of the modern Hebrew language took place. Since that time, the Academy of the Hebrew Language has extended traditional Hebrew to include Hebrew words for modern objects and concepts.

Hebrew is used mainly in Israel. Hebrew Alphabet Characteristics The Hebrew alphabet uses 27 characters to represent 22 consonants.

This is because five consonants have different shapes when they appear at the end of a word. Hebrew Alphabet Vowels are represented in two ways: Diacritic marks, called short vowels, may be used above, below or inside characters to represent vowel sounds.

Language types

Normally, however, the diacritic marks are not shown; the vowel sounds are inferred from the context. Some consonants also serve as vowels. When they are used in this way, they are called long vowels. Hebrew Long Vowels Written Hebrew has no equivalent to capital letters.

Hebrew does not have a cursive script: Unlike Arabic, Hebrew letters do not take on different shapes depending on the surrounding letters.

The five final shape letters are considered additional, separate letters of the alphabet. Hebrew Final Letters Aspects of Bidirectional Language Writing Systems This section discusses aspects of bidirectional texts, related to directionality, shaping and national numbers as well as keyboard input and compliance with common user access guidelines.

The text attributes described here also pertain to some degree to other complex-text languages such as the languages of Asia for example, Thai, Lao, Korean. Bidirectionality In the context of bidirectionality, the following are key concepts: These attributes are described below.

Segments A bidirectional text may consist of a main part that has one directionality for example, an Arabic text written from right to leftand portions that have an opposite directionality for example, an English address written from left to right.

The portion of text with a different directionality is called a segment.

Sometimes a segment with one directionality might itself have embedded or nested within it an additional segment with an opposite directionality.Theory Introduction to Programming Languages Anthony A.
