To escape characters in PowerShell, you can use the backtick (`) character. This character can be used to escape special characters like quotation marks or other characters that have special meanings in PowerShell. For example, if you want to include a quotation mark within a string, you can use the backtick character before the quotation mark to escape it and include it in the string.
Similarly, you can also use the backtick character to escape other special characters like the dollar sign ($) or the backtick character itself. This will allow you to include these characters in a string without them being interpreted as part of the PowerShell syntax.
Overall, using the backtick character is a simple and effective way to escape characters in PowerShell and ensure that your strings are interpreted correctly by the shell.
