Iceberg commit messages are wrongly encoded
The commit message for https://github.com/zeniko/processing-abstractions/commit/95680da03f1fb4c8538fdb19a02e0cd193b5bf75 contains a badly encoded umlaut.
Expected behavior: Entering umlauts and other special characters as commit messages in GT's git tool leads to correctly readable messages. E.g. submitting a commit with "Tastenkombinationen für Zoom".
Observed behavior: The commit message is wrongly encoded which is visible in Github and back in GT as well, resulting in "Tastenkombinationen für Zoom".
This issue has only been tested under Windows, where the default encoding for command line tools and the Win32 API is not UTF-8 but either the local encoding (in my case CP1252) or UTF-16.
I suspect this is due to the bug for which I backported the fix to Pharo 11 in Iceberg pull request #1877. The fix got included in Pharo 11 build 735 through Pharo pull request #17644, but Glamorous Toolkit v1.0.1972 is still based on Pharo 11 build 726.
