When escape sequences are written manually, like \u0000 in the csv file, they are not interpreted as
|
|
escape sequences but as literal characters. So, when they are read, what will be returned is the literal
|
|
string \u0000 instead of the null character. The *req.Password field that would be set using the csv
|
|
below will not match "password\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000" but will match
|
|
"password\\u0000\\u0000\\u0000\\u0000\\u0000\\u0000\\u0000\\u0000" instead.
