I am dealing with xls files for which the codepage from PHPExcel, is 21010.
These files are made by unknown software server-side.
This codepage is unknown by PHPExcel and accordingly raises an exception.
The cookie-cutter solution is to add a "case" in the PHPEcel_Shared_CodePage::NumberToName function, returning "CP1252", files are thus handled smoothly by PHPExcel.
But a solution that would avoid tinkering PHPExcel source would be better...
Did I miss a function which allows to impose the codepage to use?
