This is a Petooh Hello World

[rdebath]

From the documentation and example interpreters this is a valid Petooh "Hello World!" program.
For various reasons it appears that only one of the interpreters can run it successfully.

FYI:
Here's another interpreter that can run that code. (For a modern Ruby)
And a link to another test program: Mandelbrot set

eval 'm=Hash.new(p=0);'+ARGF.read.gsub(/[^adehkKoOru]/,'').gsub(
    /(kO|Ko|[Kk]u(dah|karek|d))/,
    'Kudah' => 'p+=1;',
    'kudah' => 'p-=1;',
    'Ko' => 'm[p]+=1;',
    'kO' => 'm[p]-=1;',
    'Kud' => '(',
    'kud' => ')while((m[p]&=255)!=0);',
    'Kukarek' => 'putc m[p];',
    'kukarek' => 'm[p]=STDIN.getbyte if !STDIN.eof;')

It seems that code is not valid and returns something like "H������� ����"

Checked with different implementations even after invalid character removal.

This is an indication of broken looping constructs in the embedded brainfuck interpreters.
As I said, almost every interpreter was broken at the time.

You can run the BF translation with any standard interpreter, and I've put the code below so you can try others than the one I linked.

>++++++++[-<+++++++++>]<.>>+>-[+]++>++>+++[>[->+++<<+++>]<<]>-----.>->
+++..+++.>-.<<+[>[+>+]>>]<--------------.>>.+++.------.--------.>+.>+.

The cleaned Petooh translation is

Kudah Ko Ko Ko Ko Ko Ko Ko Ko Kud kO kudah Ko Ko Ko Ko Ko Ko Ko Ko Ko
Kudah kud kudah Kukarek Kudah Kudah Ko Kudah kO Kud Ko kud Ko Ko Kudah
Ko Ko Kudah Ko Ko Ko Kud Kudah Kud kO Kudah Ko Ko Ko kudah kudah Ko Ko
Ko Kudah kud kudah kudah kud Kudah kO kO kO kO kO Kukarek Kudah kO Kudah
Ko Ko Ko Kukarek Kukarek Ko Ko Ko Kukarek Kudah kO Kukarek kudah kudah
Ko Kud Kudah Kud Ko Kudah Ko kud Kudah Kudah kud kudah kO kO kO kO kO kO
kO kO kO kO kO kO kO kO Kukarek Kudah Kudah Kukarek Ko Ko Ko Kukarek kO
kO kO kO kO kO Kukarek kO kO kO kO kO kO kO kO Kukarek Kudah Ko Kukarek
Kudah Ko Kukarek

Another working BF interpreter is this:

#!/usr/bin/ruby
eval 'm=Hash.new(p=0);'+ARGF.read.gsub(/./,
    '<'=>'p-=1;',
    '>'=>'p+=1;',
    '-'=>'m[p]-=1;',
    '+'=>'m[p]+=1;',
    '['=>'(',
    ']'=>')while((m[p]&=255)!=0);',
    '.'=>'putc m[p];',
    ','=>'m[p]=STDIN.getbyte if !STDIN.eof;')

Note your example HW from #38 is a trivial multiply loop, runnable by many broken interpreters.
