Question

what is symbol of long dash​

Answer 1

Answer:

_ is the symbol of Long dash

Answer 2

Answer:

The hyphen, the em dash and the en dash are the straight arrows among punctuation marks, an otherwise fairly curvaceous lot. The hyphen (-), the shortest of the three marks, is familiar (sometimes wretchedly so) to most writers. So is the em dash (—), more often called the long dash, or sometimes just the dash.
