This is a convenience template for the zero-width space character, U+200B (​).
It is completely invisible in display, but has the effect of acting as a multi-line breaking point for text inside a word that otherwise would not break. Whitespace and normal dashes (-) are already multi-line breakpoints, but this template allows the special insertion of invisible breakpoints inside words.

The zero-width space character has a higher breaking priority than the hyphen character (-), so when using it in a phrase with hyphen, it is recommended to place a zero-width space immediately after each hyphen as well.

• {{Non breaking hyphen}}
• {{Soft hyphen}} appears only if text is wrapped mid-word at specified point
• {{Word joiner}}
