Arabic diacritics in the context of "Wadaad's writing"

The romanization of Arabic is the systematic rendering of written and spoken Arabic in the Latin script. Romanized Arabic is used for various purposes, among them transcription of names and titles, cataloging Arabic language works, language education when used instead of or alongside the Arabic script, and representation of the language in scientific publications by linguists. These formal systems, which often make use of diacritics and non-standard Latin characters, are used in academic settings for the benefit of non-speakers, contrasting with informal means of written communication used by speakers such as the Latin-based Arabic chat alphabet.

Different systems and strategies have been developed to address the inherent problems of rendering various Arabic varieties in the Latin script. Examples of such problems are the symbols for Arabic phonemes that do not exist in English or other European languages; the means of representing the Arabic definite article, which is always spelled the same way in written Arabic but has numerous pronunciations in the spoken language depending on context; and the representation of short vowels (usually i u or e o, accounting for variations such as Muslim and Moslem or Mohammed, Muhammad and Mohamed).

Old Turkish or Old Anatolian Turkish (Latin Turkish: Eski Türkçe/Eski Anadolu Türkçesi, Turco-Arabic: تورکچه‌سی اسکی تورکچه اسکی انادولو), also referred to as Old Anatolian Turkic (Turkish: Eski Anadolu Türkisi, Old Turkish: انادولو تورکیسی اسکی), was the form of the Turkish language spoken in Anatolia from the 11th to 15th centuries. It is also called Turkce or Turki, it developed into Early Ottoman Turkish and Middle Azerbaijani. It was written in the Perso-Arabic script. Unlike in later Ottoman Turkish, short-vowel diacritics were used.

It had no official status until 1277, when Mehmet I of Karaman declared a firman in an attempt to break the dominance of Persian:

Rasm (Arabic: رَسْم [ræsm]) is an Arabic writing script often used in the early centuries of Classical Arabic literature (7th century – early 11th century AD). It is the same as today's Arabic script except for the difference that the Arabic diacritics are omitted. These diacritics include consonant pointing or ʾiʿjām (إِعْجَام), and supplementary diacritics or taškīl (تَشْكِيل). The latter include the ḥarakāt (حَرَكَات) short vowel marks—singular: ḥarakah (حَرَكَة). As an example, in rasm, the two distinct letters ص ض are indistinguishable because ʾiʿjām is omitted, or letters similar in shape ک ك may also become indistinguishable if the diacritics are omitted. Rasm is also known as Arabic skeleton script. This concept is somewhat similar to scriptio continua in the Latin script, where all spaces and other punctuations is omitted. The rasm form was common for writing Arabic until the early 2nd millennium.

Ḍād (ﺽ) is the fifteenth letter of the Arabic alphabet, one of the six letters not in the twenty-two akin to the Phoenician alphabet (the others being ṯāʾ, ḫāʾ, ḏāl, ẓāʾ, ġayn). In name and shape, it is a variant of ṣād. Its numerical value is 800 (see Abjad numerals). It is related to the Ancient North Arabian 𐪓‎‎‎, South Arabian 𐩳.

The letter symbol itself is a derivation, by addition of a diacritic dot, from ص ṣād (representing /sˤ/).

The Uyghur Arabic alphabet (Uyghur: ئۇيغۇر ئەرەب يېزىقى, romanized: Uyghur Ereb Yëziqi, abbr. UEY) is a version of the Arabic alphabet used for writing the Uyghur language, primarily by Uyghurs living in Xinjiang Uyghur Autonomous Region. It is one of several Uyghur alphabets and has been the official alphabet of the Uyghur language since 1982.

The first Perso-Arabic derived alphabet for Uyghur was developed in the 10th century, when Islam was introduced there. The alphabet was used for writing the Chagatai language, the regional literary language, and is now known as the Chagatay alphabet (Uyghur: كونا يېزىق, romanized: Kona Yëziq, lit. 'old script'). It was used nearly exclusively up to the early 1920s. This alphabet did not represent Uyghur vowels and according to Robert Barkley Shaw, spelling was irregular and long vowel letters were frequently written for short vowels since most Turki speakers were unsure of the difference between long and short vowels. The pre-modification alphabet used Arabic diacritics (zabar, zer and pesh) to mark short vowels. Also, the ة‎ was used to represent a short [a] by some Turki writers.
