+
+The following escape sequences are supported:
+\b, \t, \n, \f, \r, \", \\, \uXXXX, and \UXXXXXXXX
+
+To prevent a '\' from being recognized as an escape character, use either:
+
+- a ' or '''-delimited string; escape characters aren't processed in them; or
+- write two backslashes to get a single backslash: '\\'.
+
+If you're trying to add a Windows path (e.g. "C:\Users\martin") then using '/'
+instead of '\' will usually also work: "C:/Users/martin".
