== Accidental symbols ==

Unicode ~~provides symbols~~ for the standard accidentals of circle-of-fifths notation~~<ref>https://www.w3.org/2021/03/smufl14/tables/standard-accidentals-12-edo.html</ref>~~ and for the Stein-Zimmermann accidentals of neutral circle-of-fifths notation~~<ref>https://www.w3.org/2021/03/smufl14/tables/stein-zimmermann-accidentals-24-edo.html</ref>~~. Some fonts may not include all symbols, so fonts designed for musical notation, such as Bravura or Leland<ref>https://www.smufl.org/fonts/</ref>, are recommended.

The Standard Music Font Layout (SMuFL) specification provides Unicode codepoints for the standard accidentals of circle-of-fifths notation and for the Stein-Zimmermann accidentals of neutral circle-of-fifths notation. Some fonts may not include all symbols, so fonts designed for musical notation, such as Bravura or Leland<ref>https://www.smufl.org/fonts/</ref>, are recommended.

Note that there are other accidental sets for neutral circle-of-fifths notation, such as Gould arrow quartertone accidentals<ref>https://www.w3.org/2021/03/smufl14/tables/gould-arrow-quartertone-accidentals-24-edo.html</ref>and Persian accidentals<ref>https://www.w3.org/2021/03/smufl14/tables/persian-accidentals.html</ref>, but Stein-Zimmermann accidentals appear to be the most widespread.

In certain circumstances, such as when typing quickly in an online discussion, substitute symbols are used instead of the regular symbols. In addition, the Xenharmonic Wiki provides [[:Category:character templates|character templates]] to enter these symbols easily in wiki pages. The following table includes these equivalences.

=== Alternative accidentals ===

While the Stein-Zimmermann accidentals appear to be the most widespread for neutral circle-of-fifths notation nowadays, and are most likely to be understood by professional musicians, other accidental sets have been developed and used by various musicians.

Note that certain symbols may be very similar or identical to standard or Stein-Zimmermann accidentals despite having different Unicode codepoints.
