How It Works
1. Hex: write the base letter, then ͟ → a͟. Preferred when there is no named entity.
2. Decimal: same code point as 863 → ͟ after the base letter. Same result as hex.
3. CSS: use \035F in content after a letter in the string (not an HTML entity). #point::after appends a͟.
4. Typed / compared: paste the combining mark after a letter in UTF-8, or contrast U+035F (below) with U+035E (above).
Pitfalls & Tips
Common mistakes when working with Double Macron Below.
Order
Base letter first
Write a͟, not ͟a. Combining marks attach to the previous character.
͞
Below vs above
U+035F is below. U+035E is double macron above. Pick the correct code point for your notation.
_
Not an underscore
The keyboard _ is a spacing character. It does not combine under a letter the way U+035F does.
U+0331
Not a single macron below
For one combining macron below a letter, use U+0331. U+035F is the double form.
Name
No named entity
There is no &doublemacronbelow; for U+035F. Use ͟ or ͟.
CSS vs HTML
Do not mix escapes
\035F belongs in CSS strings. ͟ / ͟ belong in HTML after a base letter.
Fonts
Diacritic font coverage
Some fonts omit U+035F. Prefer a font with Combining Diacritical Marks coverage for display.
