Using special characters like umlauts in worksheet name using Aspose.Cells for .NET in C#


I have furthermore problems while writing Excel files with Cells.Net (see also issue CELLSNET-23798). I’m using version (2011/05/13).

If the name of a worksheet which a hyperlink refers to contains umlauts or other special characters, these characters are subsituted by questionmarks ("?") in the new file and the link is broken. Please find three sample files attached.

Test_SZ1 is the file the other files (Test_SZ2) refers to. Both files are originally saved with MS Excel. Result_SZ2 was saved by Cells.Net and contains the broken links.

I’d be glad if you can solve this problem shortly, because our customer (in Spain) needs this functionality really urgently.

Thank you in advance and
kind regards
