French characters (accent) displaying as symbols

Hello Friends,

We are currently facing issues with uploading of data which french accent caracters

  1. Cedilla (ç)
  2. Acute accent (é)
  3. Circumflex (â, ê, î, ô, û)
  4. Grave accent (à, è, ù)
  5. Trema (ë, ï, ü)

The accents are converted into strange symbols which should not be the case.

How do we overcome this issue.

Thanks
