Combining characters draw a line under or over the letter before them. This page offers a single underline, a double underline, an overline, a dot below, a wavy tilde below and an underline plus overline combination.
The lines connect when the font draws them correctly. In some fonts small gaps appear between letters.
No. These are Unicode characters that happen to look like styled letters, so they paste into any app that accepts text, with no font installation. Because they are different characters from normal letters, search and screen readers may handle them differently.
The underline mark is drawn per letter, and fonts differ in how well the segments join.
No. It only looks underlined. A real link needs markup the app understands.
