I was puzzled why Dan's workaround actually work. It eventually call
CreateProcessF=: 'kernel32 CreateProcessA i i *c i i i i i i *c *c'&cd
but the bytes for ucp 'copy "',fn,'" "',fn2
3!:3 ucp 'copy "',fn,'" "',fn2
.....
63003a00
5c006a00
36003000
31007400
65007300
74005c00
74006500
6d007000
5c00e600
2e007400
78007400
22002000
22006300
3a005c00
6a003600
30003100
74006500
73007400
5c007400
65006d00
70005c00
61006500
2e007400
78007400
00000000
if this data is interpreted as ansi/mbcs all those nulls will make it fails. Is
it J converts unicode to single byte (undocumented?), or CreateProcessA is
clever enough?

I agree with your observation, but when I tried the workaround, it failed
on my
computer,
shell ucp 'copy "',fn,'" "',fn2
c:\j601test\temp\?txt
The system cannot find the file specified.
0 file(s) copied.
I believe my window codepage (chinese) does not have this æ character. I
wish
that the task script can be upgraded to use wchar api to solve the
problem
for
all code pages.
