When you convert CSV to VCF manually, special characters are often removed because the file is not saved in proper UTF-8 or Unicode encoding. I faced the same issue when I tried to convert my CSV files with names containing accents, symbols and other characters. To avoid this issue, you can try using the
WholeClear CSV to VCF Converter. I switched to it because it handles UTF-8 automatically, preserves every character and lets you preview and map fields before converting. It will keep your contact details safe and export clean, error-free VCF files every time. You can try it with a free trial demo edition.
