🧠 How It Works
Hexadecimal Code
̲ uses the Unicode hexadecimal value 0332 to display the Low Line. The x prefix indicates hexadecimal format.
Decimal HTML Code
̲ uses the decimal Unicode value 818 to display the same combining mark. This is one of the most commonly used methods.
CSS Entity
\0332 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Combining character
U+0332 is a nonspacing combining mark—place it immediately after each base character to underline (e.g. u̲n̲d̲e̲r̲). Unlike the standalone underscore U+005F (_), the underline connects across characters. There is no named HTML entity.
Use Cases
The Low Line (̲) is commonly used in:
Add underlines to specific characters or words without using CSS text-decoration.
Use in phonetic transcription, dictionary entries, and linguistic symbols where underline is meaningful.
Emphasize key terms or phrases with a combining underline in headings or body text.
Create underlined blanks in forms, fill-in-the-blank content, or template placeholders.
Mark vocabulary, definitions, or important terms in educational and tutorial content.
Use in editorial markup, corrections, or published text where character-level underlining is required.
Achieve specific underline effects in typography where CSS alone is not sufficient.
💡 Best Practices
Do
- Place ̲ immediately after each character you want underlined
- Use numeric references (
̲or̲) consistently in HTML - Verify font support for combining diacritical marks across devices
- Use
text-decoration: underlinefor simple whole-word underlining when that suffices - Add semantic markup or
aria-labelwhen underline conveys meaning beyond decoration
Don’t
- Put the combining mark before the base character—order matters
- Confuse ̲ (combining underline) with _ (standalone underscore U+005F)
- Put CSS escape
\0332in HTML text nodes - Expect a named HTML entity—only numeric codes work for ̲
- Use underlining for links without clear visual distinction from emphasis
