Hi,
I have made something based on the file Upload sample and no problem when uploading binary files like pictures.
When I try to upload a specific pdf file I get this error :

No mapping for the Unicode character exists in the target multi-byte code page>

the code I use is the same
lFile := TFile.Create(lFName); lFile.CopyFrom(Context.Request.Files[0].Stream, 0);
Any idea ?

Best regards
