U0300U036F

U0300U036F refers to the range of Unicode code points from U+0300 to U+036F, which is the Combining Diacritical Marks block. This set comprises nonspacing marks that attach diacriticals to base characters to modify their appearance or meaning, such as accents, tone marks, and other phonetic or orthographic modifiers. The characters in this range are not independent letters; they are typically applied to the preceding base character in rendered text. In Unicode terminology they are classified as general category Mn (nonspacing mark) and are assigned combining classes to determine the order in which multiple marks attach to a single base.

The block contains 112 code points and includes a variety of diacritic forms, such as grave and acute accents, circumflexes, tilde, macron, breve, diaeresis and other diacritical devices. These marks are used across multiple scripts and transliteration systems to convey pronunciation, stress, or specialized typographic information. They are also used in linguistic and phonetic contexts to annotate transcription with diacritics that do not have dedicated precomposed characters.

Rendering and normalization are important considerations for these marks. Because they are combining marks, their glyphs are drawn in coordination with a base character, which can depend on font support and rendering engine capabilities. Unicode normalization forms (NFD/NFC) affect how sequences of base characters plus combining marks are stored and compared; some sequences have precomposed equivalents, while others exist only as combining sequences. Proper handling requires fonts that include the necessary diacritic glyphs and robust text shaping.

In practice, U+0300 to U+036F underpins many diacritic applications in digital text, supporting a wide array of linguistic, scholarly, and typographic use cases.
