It seems that Finnish numbers use a non-breaking space as the thousands
separator. This character (0xA0 I believe) is converted incorrectly to UTF-8
when using the UTF-8 locale and outputting numbers. This program demonstrates
the problem:

#include <iostream>

int main()
{
  std::cout.imbue(std::locale("fi_FI.UTF-8"));
  std::cout << 1224 << std::endl;
  
  setlocale(LC_ALL, "fi_FI.UTF-8");
  printf("%'d\n", 1224);
}

Compile it with "g++ tmp.cpp -o tmp -Wall". Then run "./tmp". It will output

ole:~/tmp$ ./tmp
1Â224
1Â 224

Note that libstdc++ converts the non-breaking space (you can see this character
by using .ISO-8859-1 instead of .UTF-8 in the program) into one character, which
is obviously not UTF-8, whereas libc converts the space into two.

I'm not from Finland myself, but a user of one of my programs had mysterious
crashes due to this problem - obviously they only occurs when the numbers become
greater than 1,000.
