Info from @brondani

A possible workaround is to disable the schema validation by calling packchk with the option ‘--disable-validation’.

I confirm:

$ ./cmsis-toolbox-linux-amd64/bin/packchk xxx.pdsc --disable-validation

The issue is caused by Xerxes when equalizing all possible input formats via iconv lib to UTF16 internal representation. The lib has changed in glibc between Ubuntu 20.4 and 22.4.
PackChk will be changed to build on Ubuntu 20.4 (remaining devtools left untouched), which schould solve the issue (tested, also runs on Debian 10).

There is a workaround, as already mentioned, which disables Xerxes:
--disable-validation
