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.
