 /**
  * Prepares an item before it is being written and escapes fields.
  *
  * All characters from \000 to \037 (this includes new line and tab characters)
  * as well as the backslash (`\`) and the double quote (`"`) are escaped.
  *
  * Literal Windows CRLFs (`\r\n`) are converted to LFs (`\n`) to improve cross platform
  * compatibility. Escaped single quotes (`'`) are unescaped as they should not need to be.
  * Double escaped characters are maintained and not escaped once again.
