Create a UTF-8 encoded CSV file

To ensure proper handling of special or multilingual characters, it is recommended to upload a UTF-8 encoded CSV file. This encoding format supports a wide range of characters from various languages and character sets.

How to create a UTF-8 encoded CSV file that supports special or multilingual characters, you can follow these steps

1 - Open a text editor or a spreadsheet program like Microsoft Excel or Google Sheets.
2 - Enter or copy-paste your data into the editor or spreadsheet. Make sure to include any special or multilingual characters as needed.
3 - Save the file with a .csv extension (e.g., "data.csv").
4 - If you're using a spreadsheet program, such as Excel or Google Sheets, you may need to export or save the file as a CSV file format. Look for the "Save As" or "Export" options and select CSV as the file format.
5 - Open the saved CSV file using a text editor (e.g., Notepad, Sublime Text, or Visual Studio Code).
6 - In the text editor, go to the "File" menu and select "Save As" or "Save with Encoding" (depending on the editor).
7 - In the "Save As" dialog box, choose UTF-8 as the encoding format.
8 - Save the file. This will ensure that the CSV file is encoded in UTF-8, which supports special and multilingual characters.
9 - Remember to properly handle the CSV formatting rules, such as using commas (or other specified delimiters) to separate the columns and using quotation marks if necessary.

10 - Once you have created the UTF-8 encoded CSV file, you can use it to upload on UI.

Please note - if you have uploaded a file that is not a valid UTF-8 encoded CSV file, the UI will throw the error asking for the right file.
