It would not, because those aren't the unexpected characters. JSON
strings are serializations of objects or arrays, and as such they always
start with "{" or "[", respectively. Strings values have to be in double
quotes.

The JSON syntax is very simple; take a look at the diagram on this page:
http://json.org/

The syntactically correct JSON form of your string would be

  {"partname":["Antenna"],"partdescription":["Sensor Systems Dual
  Iridium Antenna;"]}

(after removing the line break artifact).

Also note that your object contains arrays as values for partname and
partdescription. If that's not what you want, use strings instead:

  {"partname":"Antenna","partdescription":"Sensor Systems Dual
  Iridium Antenna;"}

The semicolon after Antenna looks unintentional, too, but I don't know
what you intend to do with the data.

"[" is a special character in regular expressions. If you want to use it
literally, you need to escape it:

  str.replace(/\['/g, "");
