The soft-hyphen is an invisible character that communicates to web browsers allowable line breaks within words. When a web browser wraps a line at a soft-hyphen, a hyphen is shown at line’s end.
Similar to the soft-hyphen, the zero-space character communicates allowable line breaks within strings of text. But unlike the soft-hyphen, it does not show a hyphen at line’s end. This is ideal for forcing consistent wrapping of long URLs. It also can be used to force line breaks in uncooperative web browsers after hard-hyphens in words like “zero-space” and “soft-hyphen”.
