Scenario: When we upload files that contains special characters for ex: importing values of html description field having <html> tags. After uploading the file an error will display regarding the special characters.
Solution: Choose import character encoding.
On the Scan & Upload File page of the Import Assistant, choose the type of character encoding for your CSV import. The type of character encoding you choose depends on the type of file you wish to import.
(Unicode) UTF-8 encoding — UTF-8 character encoding is the most widely used format for international users importing a CSV file created in a language other than U.S. English.
To resolve issue with importing <html> field, we can use the above mentioned encoding format.
