https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92586 --- Comment #7 from epagone --- Many thanks for looking into this, G. Steinmetz. Looking at your reduced cases, I understand that this is not related to character type. Should I remove the dependency to the meta bug "Fortran character"?

[Bug fortran/45179] Support UTF-8 (and other encodings) in the source file (.f90) for CHARACTER(kind=4)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=45179 epagone changed: What|Removed |Added CC||epagone at email dot it --- Comment #6 from epagone --- Still present in gfortran version 8.1.0. I have developed a simple workaround (although clunky) to overcome the wrong output of len() and len_trim() using kind=1 strings. I simply count how many characters are non-ASCII (comparing with achar() between 1 and 127) and then correct the output accordingly. In my (limited) tests it works, but it might have shortcomings.

A workaround is substituting this excerpt
case ('scratch')
open(newunit=funit, status=fstatus, access='sequential', &
form='formatted', iostat=istat)
with the following
case ('scratch')
open(newunit=funit, status='scratch', access='sequential', &
