Hi,

Data.txt doesn't work on Mac if it contains Japanese characters. It works on Windows. Could you confirm it does works on Mac?

Hi, I'm investigating right now.

I think the problem is that 'iswalpha' C++ function does not work correctly on Mac.

On Windows I had to use: setlocale(LC_ALL, ""); to make it work always the same

But on Mac it seems to have no effect.
I'm trying to find a solution for this.

I've just submitted a workaround for this on GitHub main branch, if the issue persists, please let me know.
