The FSR is naive and badly working. I can not force people
to understand the coding of the characters [*].

I'm the first to recognize that Python and/or Pike are
free to do what they wish.

Luckily, for the crowd, those who do not even know that the
coding of characters exists, all the serious actors active in
text processing are working properly.
