what does an a with two dots over it mean
Ä Ä (lower case ä) is a character that represents either a letter from several extended Latin alphabets, or the letter A with an umlaut mark or diaeresis.
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.
