Combining vertical line above (U+030D) is a combining mark in Combining Diacritical Marks. It does not stand alone like a normal letter — it stacks above the character that comes before it. Example: a + ̍ renders as a̍.
Remember
Character combining vertical line above (after a base)
Unicode U+030D
Hex entity ̍
Decimal ̍
CSS escape \030D
Named entity (none)
Example a̍ → a̍
Prefer ̍ or ̍ immediately after the base letter. Used in linguistic and phonetic notation. For a mark under the letter, see vertical line below (U+0329).
Using Hex Code: a̍
Using HTML Code: a̍
Using CSS Entity: a̍
Typed directly: a̍
How It Works
1. Hex: write the base letter, then ̍ → a̍ becomes a̍.
2. Decimal: same mark as 781 → a̍. Same result as hex.
3. CSS: put base + escape in one string: content: "a\030D". #point::after appends that sequence after the paragraph text.
4. Typed: in UTF-8 type a then the combining mark. Order must stay base first, mark second.
Pitfalls & Tips
Common mistakes when working with U+030D.
Order
Base letter first
Write a̍, never put U+030D before the letter you want to mark.
Named?
No named entity
HTML5 has no named entity for U+030D. Use ̍ or ̍ after a base.
vs |
Not a spacing pipe
| (U+007C) stands alone. U+030D must follow a base character.
vs U+0329
Above ≠ below
U+030D sits above the letter. U+0329 sits below — different marks.
Fonts
Combining support varies
Some fonts stack poorly. Prefer fonts with solid Combining Diacritical Marks coverage for linguistic text.
CSS vs HTML
Do not mix escapes
\030D belongs in CSS strings (with a base). ̍ / ̍ belong in HTML after a base.
A11y
Explain the notation
When a̍ appears in examples, label it as linguistic notation so readers know it is not everyday spelling.
Compatibility
Browser Support
Combining vertical line above (U+030D) and its numeric entity forms (̍, ̍, CSS \\030D) are supported in all mainstream browsers. Stacking quality depends on font support for combining marks.

Bottom line: Use ̍ or ̍ after a base letter. Use \\030D only inside CSS content strings with a base (e.g. "a\\030D").
Remember
Key Takeaways
Unicode: combining vertical line above is U+030D (decimal 781).
HTML: base first, then ̍ or ̍ (e.g. a̍).
CSS: use "a\030D" (or another base) inside content.
Meaning: combining above — not | (pipe), not U+0329 (below).
One line:U+030D → after a base letter as ̍ / ̍ / CSS \030D.
Frequently Asked Questions
Place ̍ (hex) or ̍ (decimal) immediately after a base letter — for example a̍. In CSS, use content: "a\030D". There is no named HTML entity for U+030D.
U+030D (COMBINING VERTICAL LINE ABOVE). Hex 030D, decimal 781. It belongs to Combining Diacritical Marks (U+0300–U+036F).
No. HTML5 does not define a named entity. Use numeric forms ̍ or ̍ after a base letter.
It is a combining mark, not a spacing character. It attaches to the preceding base. To show it alone in documentation, use a placeholder base such as ◌ (U+25CC) + U+030D.
U+030D combines above a letter. | (U+007C) is a spacing pipe. ˈ (U+02C8) is a spacing modifier letter — not a combining mark.
HTML entities (̍ or ̍) go in markup after the base letter. The CSS escape \030D goes in stylesheet strings (usually content on ::before/::after), typically as "a\030D".
