Editing Diacritic (section)

==Transliteration==
Several languages that are not written with the Roman alphabet are [[transliteration|transliterated]], or romanized, using diacritics. Examples:
* [[Arabic]] has several [[Arabic romanization#Comparison table|romanisations]], depending on the type of the application, region, intended audience, country, etc. many of them extensively use diacritics, e.g., some methods use an underdot for rendering [[emphatic consonant]]s (ṣ, ṭ, ḍ, ẓ, ḥ). The macron is often used to render long vowels. š is often used for {{IPA|/ʃ/}}, ġ for {{IPA|/ɣ/}}.
* [[Chinese language|Chinese]] has several [[Romanization of Chinese|romanizations]] that use the umlaut, but only on ''u'' (''ü''). In [[Pinyin#Usage|Hanyu Pinyin]], the four [[Tone (linguistics)|tones]] of [[Standard Chinese|Mandarin Chinese]] are denoted by the macron (first tone), acute (second tone), caron (third tone) and grave (fourth tone) diacritics. Example: ''ā, á, ǎ, à''.
* Romanized [[Japanese language|Japanese]] ([[Rōmaji]]) occasionally uses macrons to mark long vowels. The [[Hepburn romanization]] system uses [[Macron (diacritic)|macrons]] to mark [[long vowels]], and the [[Kunrei-shiki romanization|Kunrei-shiki]] and [[Nihon-shiki]] systems use a [[circumflex]].
* [[Sanskrit]], as well as many of its descendants, like [[Hindi]] and [[Bengali language|Bengali]], uses a lossless [[transliteration|romanization]] system, [[International Alphabet of Sanskrit Transliteration|IAST]]. This includes several letters with diacritical markings, such as the macron (ā, ī, ū), over- and underdots (ṛ, ḥ, ṃ, ṇ, ṣ, ṭ, ḍ) as well as a few others (ś, ñ).
