Hi Frank,

Are you writing to a new file or rewriting an existent file with IBM-1047 text tag?

Thanks,
Sergey

Hi Sergey,

jes this is a new file.

Curl shouldn't convert the output when -o option is using. 
1) Could you say, which version of curl you are using?
Please run one of the commands:
'curl --version'
or 
'conda list curl' 
if you are using conda.

2) If possible, could you send us the output of 'env | sort' command?

Thanks,
Sergey

Here the output of curl --version

I suggest, the reason of the conversion is the setting of _ENCODE_FILE_NEW variable.
Could you please try to unset it temporary and check if curl will be download the file without conversion. 

unset _ENCODE_FILE_NEW

Hi Sergey,

unset _ENCODE_FILE_NEW

 results in a 

t ISO8859-1   T=on  -rw-r--r-- 

and tar die not work.

When I use 

export _ENCODE_FILE_NEW=BINARY

the file is taged as

b binary      T=off -rw-r--r-- 

and tar works.

Is this intentional? Od do we have to change some settings?

Regards
Frank
