The cryptic code 0x7b is an indication, that somehow your import has either special characters, or probably in your case the character { (accolade opening). Example from here.

Hi Patrick

Thanks for your response. I hear what you are saying HOWEVER, OpenERP allowed me to import companies with that same number and thereafter it allowed me to import and match contacts to the imported companies with that same number. Why would it only be giving me errors now when I am importing quotes?

Before pointing Odoo at your CSV data:

1) Load it into Notepad++

2) From the ENCODING menu, select CONVERT TO UTF 8.

3) Save a new copy of your CSV data

I've had this problem several times before and it is due to special characters which are supported via ISO encoding but not supported by UTF8 encoding (which Odoo supports). Typically when you have a Windows platform and/or Excel conversion somewhere in the mix.

You can also expand File Format Options below where you point to your CSV and set the encoding there (if you know it), but I've had better success by re-encoding to UTF8.
