Frequently Asked Questions About Add Underline to Text
How does the underline effect work?
The tool uses Unicode combining characters (U+0300-U+036F range) placed after each character. These combine with the preceding character in supporting apps and browsers to create the underline effect.
Will the underlines appear in all applications?
Unicode combining characters work in most modern applications including social media, messaging apps, and word processors. However, some older systems or specialized software may not render them correctly.
