Can't reproduce this locally and debugging through the narrow opening provided by CI is awfully painful, but FYI:

This is xspec.bat (slightly hacked) from the DocBook xslTNG project running on Windows CI in GitHub. I've instrumented the batch file with:

    echo "XSLT:"
    echo %*

The full command is:

    java ^
        -Dfile.encoding=UTF-8 ^
        -Dxspec.coverage.ignore="%TEST_DIR%" ^
        -Dxspec.coverage.xml="%COVERAGE_XML%" ^
        -Dxspec.home="%XSPEC_HOME%" ^
        -Dxspec.xspecfile="%XSPEC%" ^
        -Dorg.docbook.xsltng.extensions.pygmentize="%PYGMENTIZE%" ^
        -Dorg.docbook.xsltng.verbose="%VERBOSE%" ^
        -cp "%CP%" net.sf.saxon.Transform %CATALOG% ^
        -init:org.docbook.xsltng.extensions.Register %*

It's particularly annoying that this looks like an encoding issue but I have explicitly specified the file.encoding and the same code on my local Windows machine does not fail.
