I just tried your MWE in directory .../äbc/test/ Ubuntu 18.04, texlive 2018, and runs fine. For texindy -V got: xindy release: 2.5.1 texindy script version: 1.13 xindy script version: 1.18 xindy kernel version: 3.0 CLISP version 2.49.92 (2018-02-18) (built on bulldog [127.0.0.1]) architecture: X86_64 and was able to run, without complain, in that directory: pdflatex test.tex texindy test.idx pdflatex test.tex and got test.pdf.
