Importing SVG doesn't work on Windows when the filename contains German special characters

[major-mayer]

Hi, I just noticed that on Windows the import of an SVG file doesn't work when it contains an German special characters like umlauts (ä, ö or ü.) or "ß". For example:

\begin{figure}[h]
    \includesvg[width=\textwidth, inkscapelatex=false]{3_Dateigröße_Vergleich.svg}
\end{figure}

Will result in:

** (org.inkscape.Inkscape:8104): WARNING **: 11:06:36.618: Can't open file: d:\checkouts\laurenz-bachelorarbeit\images\3_Dateigröße_Vergleich.svg (doesn't exist)

On my Linux machine, i never had this problem, but here on Windows it doesn't work. I am using This is LuaHBTeX, Version 1.13.2 (TeX Live 2021/W32TeX).
