Today I tried to migrate a file upload module from DataFlex 19.0 to 19.1. I ran into trouble when I tried to upload files with special characters like "éïàö" in it. In a forum message I found the following quote:

We changed the underlying technology to use the new file handler, but did that in such a way that the interface of the resource manager did not change.
I only have the samples of DF 19.1 and 20.0 on my system. With DF 19.1 the physical filename uploaded by DemoFileUpload in the upload folder is NOT correct. In DF 20.0 it is correct.

Is there a trick to solve this issue in DF 19.1?
