 If a word on a text input line contains a hyphen, a formatter may decide  
 to insert an output line break after the hyphen if that helps filling  
 the current output line, but the whole word would overflow the line.  
 If it is important that the word is not broken across lines in this  
 way, a zero-width space

 never breaks the output line after hyphens adjacent to a zero-width  
 space, after any of the other dash- or hyphen-like characters  
 represented by escape sequences, or after hyphens inside words in
