I have the text with special characters like "Gürhan Bakırküre" but when i export this as CSV and opened with excel it was showing as "Gürhan Bakırküre".
I am exporting the text using drupal data export view.
May be below link can help you - http://www.jpstacey.info/blog/2015-05-04/unicode-accented-characters-drupal-views-data-export-and-excel.
In a nutsehll, jus follow below instructions-
Copy views-data-export-csv-header.tpl.php to site's custom theme, and add a single executable line (print "\xEF\xBB\xBF";) to write the BOM:
<?php
// Print out header row, if option was selected.
if ($options['header']) {
// Begin file with UTF-8 BOM.
print "\xEF\xBB\xBF";
// Now continue to output header as normal.
print implode($separator, $header) . "\r\n";
}
Thanks
