In standard bank statmenet import, when validating the import and after mapped up this fields:

• Entry lines / effective date
• Entry lines / name
• Entry lines / credit
• Journal
• Entry lines / journal
• Entry lines / period

I get this error on the credit field:

ascii new row for relation "account_move_line" violates check constraint "account_move_line_credit_debit2" DETAIL: Failing row contains (131, 1, 2014-03-13 13:51:39.703299, 2014-03-13 13:51:39.703299, 1, 104, 8, null, null, null, null, null, -11633.07, normal, 1, null, draft, 0.00, f, null, 422, 3, 2014-03-13, 2014-02-27, 89, Overførsel utland, null, null, null, null, null, 0.00, null). 328 329 ordinal not in range(128)

What does this error message mean?
