Why does SQL Management Studio output null separated characters when saving as csv?

and can it be configured not to happen?

I'm usually finding myself saving a result of a query as a .csv and processing it later on my Unix machine. The characters being null separated makes me have to filter those chars and is a bit of a pain.

So, these are the questions:

EDIT:

Because it outputs in UTF-16 by default. Easiest conversion would then be: 

iconv -f utf-16 -t utf-8 origFile.csv > newFile.csv

Here's a piece of a hexdump of a file thus generated. Each char is followed by a null char (00):

00000cf0  36 00 36 00 32 00 0d 00  0a 00 36 00 38 00 34 00  |6.6.2.....6.8.4.|
00000d00  30 00 36 00 32 00 31 00  36 00 0d 00 0a 00 36 00  |0.6.2.1.6.....6.|

00000d30  32 00 0d 00 0a 00 36 00  38 00 34 00 30 00 37 00  |2.....6.8.4.0.7.|

I know this is an old post...but for new visitors...

When you are saving data from Microsoft SQL Management Studio, you will notice that the 'Save' button has a little arrow next to it. If you select the little arrow you can select 'Save With Encoding...' this will allow you to select the encoding you desire.

On Unix, I suggest the use of iconv -futf-16le -tutf-8 to filter your output. :-)

The file is being outputted in Unicode, not ASCII. Unicode uses twice as many bits to represent each character, hence the preceding 00's.

There might be an option to save as ANSI or ASCII, which should use 8 bit characters.
