How can I specify PHPExcel to use UTF-8?
Using PHPExcel I am trying to add chart, but as soon as I do I get "unreadable content" in Excel. With research I have found this Link
. To test this theory, I found that my generated file with PHPExcel and the Chart that open without issue on my iPad, but not on my Windows 7 x64 / Excel 2010.
How can I fix this issue?
