That's also why I grew the habit of creating file names rigorously using
ASCII chars alone AND no spaces (using underscores instead). It's so
ingrained in me that I subconsciously consider a space just a command
separator and not a legal char for filenames.
That has saved me lots of grief sometimes, at the cost of being seen

that also with documents that don't have to be processed by tools, like
PDF mail attachments). :-)
