+* Quoting.
+
+ * Arguments are delimited by white space, which is either a space or a tab.
+ * A string surrounded by double quotation marks is interpreted as a single
+   argument.
+ * A double quotation mark preceded by a backslash, \", is interpreted as a
+   literal double quotation mark.
+ * Backslashes are interpreted literally, unless they immediately precede a
+   double quotation mark.
+ * If an even number of backslashes is followed by a double quotation mark,
+   then one backslash (\) is placed in the argv array for every pair of
+   backslashes (\\), and the double quotation mark (") is interpreted as a
+   string delimiter.
+ * If an odd number of backslashes is followed by a double quotation mark,
+   then one backslash (\) is placed in the argv array for every pair of
+   backslashes (\\) and the double quotation mark is interpreted as an escape
+   sequence by the remaining backslash, causing a literal double quotation
+   mark (") to be placed in argv.
+ * In double quote mark need surround such chars:
+     & < > [ ] { } ^ = ; ! ' + , ` ~
