CSV: the first line was garbled

Dear all,

When I output CSV file with write csv function, it seems some funny charactor code injected only for the first line.
Is there any way to sanitize the column value?

  1. Opened CSV1
  2. select specific line in CSV1 and dump it to DataTable1.
  3. Write all Data Table1 context into new CSV file by “Write CSV” function…

What information do you need?
