diacriticcontaining

Diacritic-containing refers to characters that include diacritical marks—functional marks such as acute, grave, circumflex, diaeresis, tilde, cedilla, ogonek, caron, ring, and others—applied to letters to modify pronunciation, tone, or meaning. The term is used to describe any letter or symbol that carries one or more diacritics, whether as a base character with a diacritic or as a composite sequence.

In digital text, diacritic marks may be represented as precomposed characters (single code points) or as combining marks attached to base letters. Unicode supports both approaches, and normalization forms NFC (composed) and NFD (decomposed) affect comparisons and processing.

Diacritics are central to many languages. Examples include the French â, é, ø; Spanish ñ; Polish ł, ę; Czech č; Turkish ğ, ç; Vietnamese letters with multiple diacritics; Finnish ä and ö; many languages use diacritic systems to distinguish otherwise identical letters.

Rendering diacritic-containing text can involve font shaping and careful positioning of combining marks, since glyph placement can vary by font, script, and rendering engine. Other considerations include input methods, font coverage, search and collation, and accessibility for screen readers.

Overall, diacritic-containing text encompasses a wide range of written forms that rely on diacritical marks to convey precise linguistic information, with implications for typography, encoding, and software behavior.
