Is there any way to type two tilde characters in my question description without formatting my text in unwanted way?

I know I can type this shortcut at one place, like this: <kbd> Alt+`</kbd>. 
But as soon as I try to repeat this 'tilde' character anywhere in this text block, whole formatting of the sentence goes wrong. 
One way is to type single quote (') in place of tilde, but that isn't the correct way.

Any ideas?
