While the only issue here was that you do not expect any code, just "STRANGE_STRING= ....".

Can you find a string that satisfies this criteria?

You should just set the value of STRANGE_STRING to meet the previous criteria.

Python initial code:

STRANGE_STRING = 'foo'

What is not clear there? You can argue about not having to write a function and code like in almost every other kata, but what you should do is written in the description.

While critique of descriptions is a fair thing, I would sincerely recommend adjusting your general attitude a little bit.

Please adjust the description so it is clear what exactly is expected to be a code for testing. I spent (as many other solvers here) many more minutes figuring out what is wrong with the code. While the only issue here was that you do not expect any code, just "STRANGE_STRING= ....".

Not fair, really. Description level almost as bad as daspreuße's. He is the kind of bad kata description. You may be his heir soon.

I don't understand the hate. It's a pretty good example for beginners that unicode can sometimes works unexpectedly :)

Agreed. If article explained would make actual sense what the to-do is.

Including a good article explaining the concept this kata is referecing would be best. This isn't asking anyone to practice problem solving it is just wanting someone to already know what you're talking about. Not useful in current form.

best

So basically, to solve this problem, we have to look up unicode characters? What is the main learning goal of this specific problem? To be aware and familiar with the behaviour of different characters in the unicode when using certain methods?

Just find any symbol in any language which matches to this criteria. For solving this task you can use methods chr() and ord() to find a symbol (think about how use it)

I can make a hint that this kata is quite understandable and obvious for natural language learners, there is at least one widespread European language where one letter changes to two others when uppercased.

So many garbage kata lately, what is going on?

The condition of the problem is not clear to me

what is this?
