This bug may be related to 65125,
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65125 I’m not sure.
Basically it seems that 3 things are happening:
- Unicode strings aren’t being output correctly to to stdout, it seems only
the first few characters are output. This *could* be an issue related to what
gfortran thinks the encoding of the tty is. Further testing reveals that it
seems to output to a file opened with uff-8 encoding OK
- Unicode substrings retain the correct kind as long as they are not
parameters (see 65141 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65141) BUT
the resulting representation seems to be that of DEFAULT character kind. (i.e.
the characters change when a substring expression is used, characters 2-4 in
str(2:4) are different than characters 2-4 in str). This happens even when
writing to a file opened with uff-8 encoding.
