It seems unlikely that many users have a space in their paths, but it seems a use-case worth enough to be tested by CI, so that it does not have to be done manually. Ref #33929 (review) / https://mirror.b10c.me/bitcoin-bitcoin/33929/#discussion_r2590523065
So do that here, and also add a non-ASCII char while touching.
Also, fix all tests that are broken and assume no space exists in paths.

Concept ACK.
Sorry for the force pushes, but building on Windows with a space in the path is not possible, it seems, so I've just put a space in the functional test runner temp dir.
... but building on Windows with a space in the path is not possible, it seems...
True, though that appears to be a vcpkg-related issue rather than one on our end :)
A workaround is already documented here.
Feel free to grab changes from https://github.com/hebasto/bitcoin/commit/90470acdb9f3a8f27ab669824c37b1db816ca1dd, which is based on the previous iteration of this PR.
UPDATE
From the CI:
rpc_signer.py | ✖ Failed | 1 s
wallet_signer.py | ✖ Failed | 1 s
The ci fails when $FILE_ENV is not set, so fail early with a clearer
error message by setting nounset:
> bash: FILE_ENV: unbound variable
Also, add a missing quote around -DCMAKE_INSTALL_PREFIX to avoid word
splitting.
Otherwise, cmake would warn:
```
+ cmake -S /home/runner/work/_temp -B /home/runner/work/_temp/build -DCMAKE_COMPILE_WARNING_AS_ERROR=ON -DBUILD_BENCH=ON -DBUILD_FUZZ_BINARY=ON -DCMAKE_INSTALL_PREFIX=/home/runner/work/_temp/ci/scratch_ ₿🧪_/out -Werror=dev --preset=dev-mode -DSANITIZERS=address,float-divide-by-zero,integer,undefined -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_FLAGS=-ftrivial-auto-var-init=pattern -DCMAKE_CXX_FLAGS=-ftrivial-auto-var-init=pattern -DCMAKE_EXE_LINKER_FLAGS=-fuse-ld=mold -DAPPEND_CXXFLAGS=-std=c++23 '-DAPPEND_CPPFLAGS=-DARENA_DEBUG -DDEBUG_LOCKORDER'
CMake Warning:
Ignoring extra path from command line:
"₿🧪_/out"
```
Also, allow spaces in the debug log file regex in a test.
Otherwise, the test would fail:
```

This is a bug on current master, fwiw, it also happens on Linux:

@maflcko are you still working on this change?
Ah, this fell off the table. Went ahead and rebased it.
