mongo id changes its value , and i dont know why

[Lady Redhead]

So i have something like this:

db.collection.aggregation({stuff}, function(err, data){

and in my data is something like this :

id: 'X% &\u0003Vµb\u000e\u0000\u0000\u0001'

Yep so far nothing strange, but when i have an empty array and want to put the id in this array ( i change nothing ) and

just say :

array[i] = data[i].id

then my id looks different , it looks like this :

'X% &Vµbe'

So it takes the letters and symbols and forget the rest ....

But why ?

first, i would post this question in mongodb-user forum, you will get more responses and answers there.

what is this code?  is this in the mongo shell?

As Dwight says you should to get this to mongodb-users.

As a pointer  \uXXXX marks your text in javascript as an unicode character.

Unicode 0 to 20 - \u0000 to \u0020 - are not printable characters.

You text contains:

\u0000 - 0x0000 = NULL
\u0001 - 0x0001 = SOH , start of heading, for teletypes, etc ...
\u0003 - 0x0003 = EXT , end of text for teletypes, etc ...
