diacriticmarked

Diacriticmarked is an adjective used to describe text that contains diacritic marks—glyphs added to letters to modify their pronunciation, tone, stress, or meaning. Such marks are called diacritics and appear in many writing systems. A diacriticmarked string may feature one or multiple diacritics on one or more letters, or may use combining marks that attach after the base character.

Diacritics serve various functions: in phonology they indicate vowel quality or consonant modification; in writing systems they can distinguish homographs; in certain languages they encode tone, length, or nasalization. Examples include the acute (é, sí), the grave (è), the circumflex (â), the umlaut/diaeresis (ä), the tilde (ñ, ã), the cedilla (ç), the caron (č), the ring (å), and the dot above (İ).

Computational aspects: Unicode supports diacriticmarked text via precomposed characters or base-plus-combining marks; normalization forms NFC and NFD affect equality and search. Systems must handle diacritic sensitivity in sorting and indexing; input methods and fonts must render combining marks correctly for legibility.

Historically, diacritics arose in scribal practice and were adopted into national orthographies. Today diacriticmarked text is common across languages using Latin scripts and even in transliteration schemes for non-Latin scripts. The term emphasizes the visible marks that modify characters rather than the underlying base letters.
