U+0308
A combining mark attaches to a neighboring character. It can sit above or below a letter, and several marks can occur together.
Browse the individual mark guides, or copy a combining mark from the reference below.
One appearance, different encodings
é can be written as U+00E9, or as e (U+0065) followed by COMBINING ACUTE ACCENT (U+0301). These forms are canonically equivalent. Unicode normalization can convert between composed and decomposed forms.
A spacing accent symbol is not the same character as a combining mark. The dotted circle in Unicode charts shows where a mark sits; it is not part of the mark itself.
Marks in this reference
This list covers the 25 distinct marks in our precomposed A to Z Latin data. It is not a catalog of every Unicode combining mark.

Still under editorial review
These families remain available as individual Unicode records in the explorer.
- inverted breve: U+0311 and its canonical composites are verified, but the source pack does not yet establish a sufficiently scoped current versus historical account of South Slavic accentology and its distinction from Greek perispomeni. Publishing from character names alone would overstate the usage evidence.
- hook below: U+0321 and U+0322 are verified, but a complete account of historical palatalized and retroflex hook notation, its current replacements and valid representative combinations has not been established from the authoritative phonetic sources. Their Unicode records remain searchable in the explorer.
