And why would that not be valid? isValidPath and isValidFilename are quite
specific about what they think are valid path/file names, and having a # in
a file name is perfectly legitimate. They do have some extra restrictions
for Windows, since Windows is a lot pickier about its filenames than the
rest of the world, but # is not one of the characters listed as invalid:

https://dlang.org/phobos/std_path.html#isValidPath
https://dlang.org/phobos/std_path.html#isValidFilename

It would be invalid to have # as a drive name, but it's perfectly legal in a
filename or directory name.
