Solution

Add with explanations to ErrInvalidString error in

neofs-node/pkg/util/locode/record.go

Thus, a complete UN/LOCODE is a combination of a 2-character country code and a 3-character location code

NeoFS node supports only complete UN/LOCODE separated by whitespace between country code and location code.
