In the encodin, pay attention to the special letter, the spacing and the digits ;)

check the length of the encoded character, it should be == 8

I'd still agree with headliner.

Several subproblems requiring multiple functions and transformations (whether labeled or anonymous) is probably a 5+. This was definitely more time & brain consuming than any 5 I've done so far.

check spaces in sentence

I didn't try to decode it but the encode works for short sentences only

Try to do it step by step and not with a one liner, then you'll find your mistake

@SFM61319 your solution works fine and @headliner your solution is just wrong.

Same dude. I did exactly what they told me to, but the encode only works for short sentences and not long, number, special sentences.
decode works fine for me tho.

Cheers!

Great job, thank you man! :)

done.

Do what ever you want to make the kata better. I'm not good in writing descriptions :))

a bit big, yeah. But yes, something like that is perfect. But you should imo put that higher in the description (adding information bits by bits makes it lose its consistency/logic, spreadnng the useful info in different places).

Can I make a sweep on the desription and move/rewrite some parts?

Ok, understood!

Check out new picture in description, have you thought of something like that?
Picture is big, I'll make it a bit smaller

Did I set estimated rank to 6kyu, if so then I made a mistake and I apologize...

no, yours was 5 (iirc). But the two other averages were 6. Hence my choice. ;)
