what does an em dash symbol look like
Dash The dash is a punctuation mark that is similar in appearance to a hyphen or minus sign, but differs from both of these symbols in both length and function. The most common versions of the dash are the en dash (–) and the longer em dash (—), whose names historically were loosely related with the width of a lower-case n and upper-case M, respectively, in commonly used typefaces.
Superman logo In its original inception in Action Comics #1, Superman's symbol was a letter S with red and blue on a yellow police badge symbol that resembled a shield. The symbol was first changed a few issues later in Action Comics #7. The shield varied over the first few years of the comics, and many times was nothing more than an inverted triangle with an S inside of it.[1][2]
