[fpc-devel] Linux Binary - Socket Output affected by SystemCtl, HELP!

Ok.

I'd suggest, as a quick and horrible temporary hack/test, replace this 
direct binary call with a shell wrapper, lets name it e.g. 
coderunner2.sh, containing something like:

#!/bin/sh
echo "LANG=$LANG" >>/tmp/test.txt
echo "LOCALE=$LOCALE" >>/tmp/test.txt
export LC_ALL=C
/usr/local/bin/coderunner2

(Put it into /usr/local/bin/ as otherwise systemd might refuse it; I 
suppose the script is simple enough to be self-explanatory)

Sure.

That proves the problem is unrelated to sockets. Is is related to 
string/encoding handling.


HTH...
