+Enable or disable the interpretation of symbolic representations of special

+.br
+Translations can occur with quoted input in 3 modes:
+.br
+ "in_double_quotes" translates only inside " quotation.
+.br
+ "outside_single_quotes" translates not inside ' quotation.
+.br
+ "with_quoted_input" translates all input text.
+.br
+With the start program arguments there is mode:
+.br
+ "with_program_arguments" translates all program arguments.
+.br
+Mode "off" is default and disables any translation.
+Mode "on" is the same as "with_quoted_input:with_program_arguments".
