Yes it would. Obviously the solution is to use colons as the path separator,
like in Classic Mac OS (and a few others).

And then, as sure as water is wet, you'll complain that you want to use : in
your file names.

*Whatever* record separator you choose to use, whether it is slash / or
backslash \ or colon : or Ctrl-^ RS or U+113A HANGUL CHOSEONG SIOS-PHIEUPH,
you can't *also* use it as a non-record separator.

I suppose one might invent an escaping scheme, so that you can escape the
record separator, and another escaping scheme so you can escape the escape
and prevent it from escaping the record separator. That would work.

But it's complex and error prone and people will get it wrong, and the
people who designed the Unix file system didn't think the extra complexity
was worth the benefit. If you disagree, feel free to design your own file
system, and if people prefer yours, they'll use it.

Its not just Unix. As far as I know, *no* file system, from any operating
system, has bothered to introduce an escape character so that file names
can include the path record separator. Not Unix, not Windows, not OS X, not
classic Mac OS, not Solaris.
