Escape the string Crime d'Amour containing the ' special character:

Crime d\'Amour

The string above contains a quote, so the ' needs to be escaped when quoting it:

'Crime d'\''Amour'

Include leading or trailing whitespaces using quoting:

'  this string starts and ends with whitespaces  '

Escaping and quoting can be mixed together:

' The string '\'string\'' is a string '

To include a literal '\' you can use either escaping or quoting:

'c:\foo' can be written as c:\\foo
