It won't solve the problem if you have that X11 file on your system,
because we read it before we get to the code I changed.

But it requires the eo.UTF-8 locale to be available, AFAIU, and for
that reason somehow didn't work for the OP.  I don't think I
understood why it didn't work for him.  I still hope the OP will come
back and help us understand that.

If we think 2) will work for (almost) everyone, maybe the problem is
not serious enough to have to decide between two extremes?
