Transit Package Handlere creates wrong filename for return package

Hi all, have any of you experienced problems with the TPH when the filename contains special characters?

That's what the filename looks like before I import the project in Trados:

In Trados, the correct filename gets generated.

In the return package the filename remains as is and will be converted into a different filename when the package gets reimported.

In order for the package to work, it would need to contain the file with the same filename as in the out-package. Is this a setting within Trados or is it a problem with TPH?

Thank you for letting me know.

Best regards
Karin
