I having a Excel document with a data table containing Chinese characters. I am trying to export this Excel spreadsheet to a CSV file for importing into a MySQL database.
For some people this solution may work: https://support.geekseller.com/knowledgebase/utf-8/
When saving csv, go to lower right Tools > Web Options > Encoding > Unicode (UTF-8)
Or this SO answer: just use Google Sheets to save csv as unicode: Excel to CSV with UTF8 encoding
