File Manager Document Macro vs dot in filename

Files usually have filename extensions (.pdf, .docx, etc) and when uploading a file in File Manager the filename is kept intact, so the page name is the same as the file's name.

Trying to use the File Manager Document macro, it seems impossible to build a working page reference.

FileManager.filename.pdf
FileManager.filename\.pdf
FileManager.filename\\.pdf
FileManager.filename%2epdf

All of those result in a white box, so the page ref isn't found.

If I rename the file in File Manager, removing the extension, it works as expected, but that's not a sane way to deal with the issue (ext will be missing for downloads, too; no file type icon in File Manager, etc)

Is there any trick to escape the dot?
