Thanks very much for this very detailed description of the current situation (very much appreciated)!

I googled for codepage setting and came up with this entry: https://learn.microsoft.com/en-us/windows/apps/design/globalizing/use-utf8-code-page. Is that the API you meant?

From the above linked page I gather that a manifest file (setting UTF8 codepage) can be attached to the executable (strawberry-perl) with mt.exe. I had naïvely checked that out with perl.exe, but it did not work, which could be my fault.

I will proceed with looking into the Strawberry code base as time permits. Edit: I found this related issue from ikegami (from 2020): https://github.com/StrawberryPerl/Perl-Dist-Strawberry/issues/18.

Edit2: There is also an issue in the upstream perl repo: https://github.com/Perl/perl5/issues/17094.

Thanks again for setting me on the right track.
