Source: unicode-data Version: 16.0-2 Since unicode-data 10.0.0-1 in 2017, the Debian unicode-data package has consistently used a 3-part version number (10.0.0) for the upstream version. Could you reupload unicode-data 16.0-2 as 16.0.0-1?
This matches the upstream number seen at https://www.unicode.org/versions/Unicode16.0.0/ The python-unicodedata2 build assumes a 3-part version number and it might be better to reupload unicode-data then to try to work around this issue in the python-unicoedata2 packaging. Thank you, Jeremy BĂcha
