Thank you, but I'm still missing a clue. The reason I remain confused is perlop: 
The following escape sequences are available in constructs that interpolate, and in transliterations:

    Sequence Note Description
    \t tab (HT, TAB)
    \n newline (NL)
    \r return (CR)
    \f form feed (FF)
    \b backspace (BS)
    \a alarm (bell) (BEL)
    \e escape (ESC)
    \x{263A} 1,8 hex char (example: SMILEY)
    \x1b 2,8 restricted range hex char (example: ESC)
    \N{name} 3 named Unicode character or character sequence
    \N{U+263D} 4,8 Unicode character (example: FIRST QUARTER MOON)
    \c[ 5 control char (example: chr(27))
    \o{23072} 6,8 octal char (example: SMILEY)
    \033 7,8 restricted range octal char (example: ESC)
Should this not be "\n\003\036\025"?
