Underline text so the line survives a paste
Underlining normally needs formatting the destination supports, which rules out most social bios, usernames and chat fields. This generator underlines text using Unicode combining marks, placing an underline stroke on each character so the line is part of the text itself and holds up when pasted where formatting would be stripped.
How the underline is attached
A combining low line is a mark that sits under the character before it. Applying one to each letter draws a continuous underline beneath the word, built from the characters rather than added as a style. That is what lets the underline travel with the text into places an underline button cannot reach.
Decoration, not semantics
Underlined Unicode text is useful for emphasis in fields with no formatting, but it carries the usual caveat: the combining marks make the text harder for screen readers and search to process, and an underline can be mistaken for a link. Use it as visible decoration rather than for words that need to be machine-read or that might look clickable. The generation runs entirely in your browser.

Frequently Asked Questions
How does the underline survive pasting?
It is drawn with Unicode combining marks under each character, so the line is part of the text rather than formatting the destination could strip.
Where is it useful?
In fields with no formatting, such as social bios, usernames and chat, where you still want underlined emphasis.
Any downsides?
The combining marks make text harder for screen readers and search, and an underline can be mistaken for a link, so keep it for visible decoration.
Does it underline spaces too?
The underline is applied across the characters so a word reads as continuously underlined.
Is my text uploaded?
No. The generation runs entirely in your browser.
