The tilde (~)
Draw a squiggly line under the 0.
No.
A number of computer programs and phone apps have built in spell-checkers. If the word you have used is not one which the computer/phone recognizes, it marks it with a squiggly red line. This does not necessarily mean that you have spelled the word wrong: it could be a proper noun, or a slang word, or a spelling which is not used by the geek who created the program. The squiggly line is only an alert; you must decide if the word actually needs changing.
It is a line that twists and turns, not astraight line.
/\/\/\/\/\/\/\/\/\/\/\/\/\/\ is the line
So they know that it's a person that's on line, not a computer virus or something.
I drew a squiggly line.
It is in fact not a squiggly line.. But a small outline of the state. This is done to combat counterfeitting and also as a tracking method.
