I'm currently working on a vfpage that can upload records using CSVs similar to
this project. But, the records in the CSV may contain accented characters from spanish alphabet. So, when I attempt to upload a csv with accented characters, those characters will instead look like a question mark (?) or unrecognizable.
Yes I have tried base64encoding and I'm avoiding the process of going through notepads or notepad++ to correct the characters before upload.
I really appreciate the help guys if you have any idea about this.
