Underline Text

This tool draws a line under every character of your text using the Unicode combining mark U+0332 (COMBINING LOW LINE). Unlike an HTML <u> tag or a font, the result is plain text that works anywhere — social posts, chat, docs, code comments — with no formatting support required.

How it works:

• Each character gets the combining low line inserted right after it; the mark attaches to the preceding base character, so the underline is drawn per-character.
• This is not HTML/rich-text underlining — it is real Unicode text that survives copy-paste into apps which strip formatting.
• Letters, digits, punctuation, spaces, emoji, and CJK all get underlined — the mark applies universally.
• Because it relies on a combining character, the exact appearance depends on the font/renderer, but all modern platforms render it correctly.

Good to know:

• Use it for emphasis where bold/italic aren't available, or to mark key terms in notes.
• To remove the underline later, delete the invisible combining characters (a find-and-replace on ̲ restores the original).
• Screen readers may not recognize the underline; avoid it for accessibility-critical content.
