I saw something similar before, but unfortunately, the patch below
doesn't fix it.

cpu% fn 'file?' { test -f $* }
cpu% 'file?' /LICENSE
cpu% echo $status

cpu% 'file?' /foo
cpu% echo $status
test 145387: false
cpu% rc
cpu% 'file?' /LICENSE
rc: can't open /env/fn#file
?: bad character in file name: '/env/fn#file
?'
file?: '/bin/file?' file does not exist
cpu% 'file?' /LICENSE
file?: '/bin/file?' file does not exist
cpu% unicode 

0001
cpu%
