Underline and line mark styles

Line styles add a mark above, below or through ordinary letters using Unicode combining characters. Underline and strikethrough are the familiar ones, but the catalog also includes dotted, dashed, wavy, double and arrow-shaped marks, each with a different visual weight.

These are modifiers rather than complete alphabets. Applied alone they underline plain text; combined with a base letter style they produce a stronger effect. Combining marks are the least consistently rendered characters on the site, so a line that looks clean on one device may sit too high, too low or disappear on another.

How lines text works

The text on this page is Unicode, not a font file. Each style replaces letters with look-alike characters, which is why the result can be pasted into a bio, a caption or a chat without installing anything. The page renders real output rather than a picture of output, so the copy button gives you exactly what you see.

Support is decided by the receiving app, not by this page. A style built from common mathematical or Latin characters is likely to render widely; a style built from rarer symbols or long stacks of combining marks is more likely to be stripped or drawn as an empty box. Check the support label on each row and preview the result in the field you plan to use.

If a style does not appear correctly, the problem is usually the destination font. Try a simpler letter swap, or use the font studio to turn the styled text into an image that nothing can flatten. For a broader comparison, see the style guides or browse the symbols, emoji and kaomoji libraries.

Common questions

How does underlined Unicode text work?

A combining underline character is placed after each letter. The renderer draws the mark beneath the preceding character. Because the mark is a separate code point, the text remains copyable, but its position depends on the app and font.

Why does the line sit in the wrong place?

Combining marks are positioned by the font and the text layout engine. Different devices use different fonts and may stack or shift the mark. There is no way to control the exact offset from plain text.

Should I use a line style in a username?

Usually not. Many username fields either strip combining marks or count them as extra characters, and the result can look broken. Use a line style for display text where you can see the final rendering.
