"No source files for package" in a directory with accent characters

Tue Sep 3 17:06:27 UTC 2019

This is the title of an issue reported for the Maven plugin[1]

Based on the analysis some involved developers came to the conclusion that  
the outputFileEncoding for Java 9, 10 and 11 was changed to UTF-8, but  
since Java 12 it behaves again like Java 8.

Can this be confirmed with the related ticket or are we facing a different  
issue?
