Using Hex Code: o͖
Using HTML Code: o͖
Using CSS Entity: o͖
Typed directly: o͖
How It Works
1. Hex:U+0356 → ͖ after the base letter. The browser combines them into o͖.
2. Decimal: same code point as 854 → ͖. Same result as hex.
3. CSS: use \0356 in content (not an HTML entity). #point::after appends the mark below the letter o.
4. Typed: in UTF-8 you can type the base letter and the combining mark directly — same visual result.
Pitfalls & Tips
Common mistakes when working with combining Right Arrowhead Up.
Order
Base letter first
Write o͖, not ͖o. Combining marks follow the base.
Named?
No named entity
HTML5 does not define a named entity for U+0356. Use numeric forms.
Shape
Double diacritic
U+0356 combines a right arrowhead with an up arrowhead. It is not the same as U+0350 or U+0355 alone.
Position
Sits below
Despite “Up” in the common title, the official mark sits below the letter (Unicode combining class Below).
A11y
Explain the mark
Screen readers may skip or misname combining marks. Add a note or aria-label when the diacritic carries meaning.
CSS vs HTML
Do not mix escapes
\0356 belongs in CSS. ͖ / ͖ belong in HTML after the base letter.
Fonts
Diacritic coverage
Some fonts omit U+0356. Prefer Charis SIL, Noto Sans, or another phonetics-capable face.
