Hello, after porting an existing wiki-installation from OpenBSD to Windows Server 2003 we have got the problem that files with german special characters aren't uploaded correctly. Just an example: I uploaded the file "test_ö_ä_ü_Ö_Ä_Ü_ß.jpg". No error message is shown and when the link below the upload-success-message (Test_ö_ä_ü_Ö_Ä_Ü_ß.jpg (12KB, image/jpeg) ) is clicked, this is the result: Not Found The requested URL /wiki/images/e/eb/Test_ö_ä_ü_Ö_Ä_Ãœ_ß.jpg was not found on this server. The file on the (NTFS-)filesystem is named "Test_ö_ä_ü_Ö_Ä_Ãœ_ß.jpg". I already tried to change $wgLegalTitleChars = " %!\"$&'()*,\\-.\\/0-9:;=?@A-Z\\\\^_`a-z~\\x80-\\xFF"; to $wgLegalTitleChars = " %!\"$&'()*,\\-.\\/0-9:;=?@A-Z\\\\^_`a-z~"; to disable the last 127 ASCII characters (also including ö, ä, ü, Ö, Ä, Ü, ß). With this change, I can avoid that persons can upload files with those characters. Those characters will be replaced by "-". But -of course- it also isn't possible to create articles with special characters anymore, which is rather unacceptable. On my Windows Server 2003 I am running Apache 2.0.55 (Win32) PHP 4.4.2 MySQL 5.0.24 I would be very pleased if someone can help and tell me how I can provide this wiki with the ability to use german special characters on Windows Server 2003. Thank you in advance, kind regards, Frank
