AFAICT the substring problem occurs for PARAMETER only:
program test3
INTEGER,PARAMETER :: ucs4 = selected_char_kind("ISO_10646")
CHARACTER(3,UCS4),PARAMETER ::
unip=CHAR(INT(Z'5e74'),UCS4)//CHAR(INT(Z'6708'),ucs4)//CHAR(INT(Z'65e5'),ucs4)
character(3,UCS4) :: uni
uni = unip
open(6, encoding="utf-8")
print *, uni
print *, uni(2:2)
print *, unip
print *, "'",unip(1:1),"'"
end program test3
gives at run time

Try this:
program test3
INTEGER,PARAMETER :: ucs4 = selected_char_kind("ISO_10646")
CHARACTER(3,UCS4),PARAMETER ::
unip=CHAR(INT(Z'5e74'),UCS4)//CHAR(INT(Z'6708'),ucs4)//CHAR(INT(Z'65e5'),ucs4)
character(3,UCS4) :: uni
uni = unip
open(6, encoding="utf-8")
print *, uni
print *, uni(2:2)
print *, unip
print *, "'",unip(1:1),"'"
call write_it(unip(2:2))
contains
subroutine write_it(str)
character(len=*,kind=UCS4) ,intent(in) :: str
print *, str
end subroutine write_it
end program test3
I get this error message when I try to compile:
$ gfortran test3.f90
test3.f90:11.16:
call write_it(unip(2:2))
1
Error: Type mismatch in argument 'str' at (1); passed CHARACTER(1) to

Similarly if I try to use a substring in an if statement:
program test3
INTEGER,PARAMETER :: ucs4 = selected_char_kind("ISO_10646")
CHARACTER(3,UCS4),PARAMETER ::
unip=CHAR(INT(Z'5e74'),UCS4)//CHAR(INT(Z'6708'),ucs4)//CHAR(INT(Z'65e5'),ucs4)
character(3,UCS4) :: uni
uni = unip
open(6, encoding="utf-8")
print *, uni
print *, uni(2:2)
print *, unip
print *, "'",unip(1:1),"'"
if ( unip(2:2) == CHAR(INT(Z'6708'),ucs4)) print*, unip(2:2) ! This SHOULD be
true
end program test3
I get the following error:

My apologies, I responded too quickly to Dominique... I thought we were talking
about: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65125 and failed to realize
that this was something (related?) different that that bug. I'll work on a more
concise version of the reproducer I attached here, to try to illustrate this
issue more clearly. I might not get to it until later tonight or tomorrow,
however.

--- Comment #5 from Zaak <zbeekman at gmail dot com> ---
Alright, I agree with Dominique, this bug report was erroneous on my part. In
the two follow up programs I posted, (modifing Dominique's) I accidentally used
`unip` substrings instead of `uni` substrings.
In my original post the issue is that I didn't open stdout with
`encoding='utf-8'` and gfortran doesn't allow unicode/utf8 encoded source files
(trying to add `-finput-charset=utf8` to the gfortran flags results in an
error: "f951: warning: command line option '-finput-charset=utf8' is valid for
C/C++/ObjC/ObjC++ but not for Fortran")
I think I'll close this unless anyone objects.
