Thanks for the tip! You may be on the right train of thought as the extra mull characters only appear in certain circumstances (such as copying paths from the Windows File Explorer path bar, and not when copying the same path from a text file, for example.

Perhaps I'll have to give the W32 config a go - I had mainly used the WSL2 build primarily out of familiarity in Linux and convenience (I'll have to read up on the W32 side), but the encoding issues and GTK-hang-on -disconnect bug can be quite annoying!

Generally, are these bugs investigated when someone with time and knowledge happens to stumble across them? Thanks.

I am, but I am occupied enough that my inbox has become distinctly
fickle. I sould simply suggest that the OP use the W32 configuration in
preference to WSL2, whose implementation is, from what we've observed
here, sorely wanting. Emacs's selection access is slightly more direct
than most other GTK programs', and has a penchant for revealing encoding
issues that are otherwise concealed by the high-level GTK clipboard API,
which auto-detects coding systems and transparently disregards decoding
failures.
