What steps will reproduce the bug?

Couldn't find a tracking issue for this one.

There are places in the source that handle std::filesystem::path objects, and on Windows, this involves conversion between UTF-8 strings and wchar-based paths. This can lead to path corruption, as previously discussed.

One example of this is #56049, which has an open PR to fix this specific usage. However, #58764 has just been reported, which affects a completely different area of the API. There are other examples of usage elsewhere in the source.

It feels like this probably needs a library-wide approach – even if not removing std::filesystem::path entirely as previously discussed, then at least some sort of internal wrapper API to abstract out potential footguns.

Beginne mit der Durchsicht von #56049 und #58764 und suche anschließend im Quellcode nach weiterer Verwendung von std::filesystem::path. Als abgeschlossen gilt die Aufgabe, wenn ein für die gesamte Bibliothek abgestimmter Ansatz für den Umgang mit Windows-Pfadkonvertierungen und die Auflösung der betroffenen Verwendungen, einschließlich dieser Beispiele, vorliegt.
