Out of curiosity I've tried to manually run this on Windows and 
it seems that Java generator for these numbers files is "broken", 
the resulting count or print runs fine for both Java and D 
versions provided in your D branch, but fails with generated 
files.

D version complains about bad utf8 encoding.
I've opened the generated file in text editor and it is UTF-16 
(little-endian with BOM).

Tried with adoptium jdk 17 and 21 (former openjdk), but I guess 
it doesn't matter since UTF-16 is default on Windows.
