Using latest Papaparse to parse large CSV files.
It handles double quotes in the value but not when value starts with double quotes.

Using this code:

const parsePromise = new Promise<void>((resolve, reject) => {
    Papa.parse<Equipment>(fileStream, {
        header: true,
        delimiter: "t",
        dynamicTyping: true,
        skipEmptyLines: true,
        step: (result) => {
            const rowData = {
                vehicle_id: result.data.vehicle_id,
                schema_id: result.data.schema_id,
                option_id: result.data.option_id,
                record_id: result.data.record_id,
                location: result.data.location,
                data_value: result.data.data_value,
                condition: result.data.condition,
            };
            entities.push(rowData);
            console.log(rowData)
        },
        complete: () => resolve(),
        error: (error) => reject(error),
    });
});

If I have the following csv data:

vehicle_id  schema_id   option_id   record_id   location    data_value  condition
425972620240523 15102   1266    7700    W   "Första hjälpen"- förbandslåda med varningstriangel, 2 varselvästar 
425972620240523 15104   1266    7700    W   W   
425972620240523 15101   1266    7800    INT S   
425972620240523 15102   1266    7800    INT medical kit, warning triangle, 2 safety vests   
425972620240523 15104   1266    7800    INT INT 
425972620240523 15101   1267    7900    W   S   
425972620240523 15102   1267    7900    W   Papperskorg (borttagbar)    

It outputs

{
  vehicle_id: 425972620240523,
  schema_id: 15102,
  option_id: 1266,
  record_id: 7700,
  location: 'W',
  data_value: 'Första hjälpen"- förbandslåda med varningstriangel, 2 varselvästartrn' +
    '425972620240523t15104t1266t7700tWtWtrn' +

    '425972620240523t15102t1267t7900tWtPapperskorg (borttagbar)trn',
  condition: undefined
}

If I move the first double quote as in:

vehicle_id  schema_id   option_id   record_id   location    data_value  condition
425972620240523 15102   1266    7700    W   Första "hjälpen"- förbandslåda med varningstriangel, 2 varselvästar 
425972620240523 15104   1266    7700    W   W   
425972620240523 15101   1266    7800    INT S   
425972620240523 15102   1266    7800    INT medical kit, warning triangle, 2 safety vests   
425972620240523 15104   1266    7800    INT INT 
425972620240523 15101   1267    7900    W   S   
425972620240523 15102   1267    7900    W   Papperskorg (borttagbar)    

The result is correct:

{
  vehicle_id: 425972620240523,
  schema_id: 15102,
  option_id: 1266,
  record_id: 7700,
  location: 'W',
  data_value: 'Första "hjälpen"- förbandslåda med varningstriangel, 2 varselvästar',
  condition: null
}
{
  vehicle_id: 425972620240523,
  schema_id: 15104,
  option_id: 1266,
  record_id: 7700,
  location: 'W',
  data_value: 'W',
  condition: null
}
....

How can Papaparse handle values starting with a double quote?
