One line too, but less evil:

astring.gsub!(/\\[nt\\\"]/) { |x| eval "\"#{x}\"" }

=>

astring = '[\nA\tB\\\\C\"D]'
puts astring, astring.inspect

astring.gsub!(/\\[nt\\\"]/) { |x| eval "\"#{x}\"" }
puts astring, astring.inspect

==>
[\nA\tB\\C\"D]
"[\\nA\\tB\\\\C\\\"D]"
[
A       B\C"D]
"[\nA\tB\\C\"D]"
