Frequently Asked Questions
How does the underline effect work?
We insert the Unicode combining low line (U+0332) after each character. When rendered, it draws an underline that mirrors traditional formatting.
Will this underline display everywhere?
Most modern browsers and apps render combining marks correctly. A few legacy systems may show separate underscores—test in your target app if critical.
Can I underline only part of my text?
Yes. Paste or type the portion you want underlined and combine it with normal text before or after copying.
Does this replace HTML <u> tags?
When HTML isn’t allowed, Unicode underlines are a fast alternative. Use semantic HTML where possible for accessibility.
Is it reversible?
Simply delete the combining marks or paste the output back into the generator and clear it.
Is my text stored anywhere?
No. Everything runs locally, so your content stays private.
