I recently pulled the latest emacs-30 branch (f47297782bdb5e5a07e02f119c8013d11f7d7fae), and I'm building emacs using MSYS2 mingw64 on Windows.
With a build on this branch, certain symbols (from the nerd-icons package) were rendering as boxes and not their actual symbol. I suspected that this was because gdi was being used, and indeed using describe-char on any character shows me a font starting with `gdi:`, indicating the uniscribe or harfbuzz are not being used. This is not the case on the emacs-29 branch, where I see `uniscribe:` instead (and the symbols render correctly). I was not able to get harfbuzz to load on that branch, which is why I was trying emacs-30 to see if something was different there. To investigate this, I first used procmon to look at the syscalls to see if anything was trying to load libharfbuzz-0.dll, and I did see it in the trace I took, however the callstack was an OS callstack, and not from where I expected (src\w32uniscribe.c:syms_of_w32uniscribe_for_pdumber). I rebuilt with debug symbols, and set a breakpoint in that function - it was called once, but `initialized` was false so the LoadLibrary calls never ran. I'm not too familiar with how pdumper works, or the emacs source in general, so I'm not sure what the actual root cause is here. I did a bit more debugging to see when `initialized` was set to true, and it does get set later during initialization. I noted that I do not have a .pdmp file in my installation direction, which it seems to be trying to load during startup. One more piece of information: attempting to yank any text results in the error: `Coding system is invalid or doesn't have an eol variant for dos line ends: nil` This error occurs when starting with -Q and attempting to yank any text. If I call `(set-selection-coding-system 'utf-16-le)`, it resolves the issue. However, I didn't have to do this in emacs-29, so this makes me think something has possibly broken with init on Windows, since I believe this is not supposed to be nil by default? I'm happy to assist by providing any additional info if needed!
