If you want to check your performance, you know you can run

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.
It's not Java writing the file, it's the bash script
[`benchmark.sh`](https://github.com/renatoathaydes/prechelt-phone-number-encoding/blob/master/benchmark.sh#L31):
```
java -cp "build/util" util.GeneratePhoneNumbers 1000 >
phones_1000.txt
```
Java is just printing to stdout. I wasn't aware that piping like
this would use the OS default encoding. Unfortunately I don't
have Windows here, but try to change the encoding used by the
bash script maybe?
