This one turned out to be trickier than it seemed at first!
Honestly, I never would’ve thought about urinals in this context.😂
The story was hilarious and really added to the fun. Loved it, thanks for the great challenge!

Very nice kata on encoding.

use str.isdecimal()
for checking if it's Numeric mode (0-9) in Python

Thank you. Added fixed test to C#, Java, JavaScript, Julia, PHP, Python, Ruby and TypeScript.

Thank you. Fixed.

LGTM, Approved!

[Python] update to new test framework: https://www.codewars.com/kumite/649ec120b3856c10bcc2e779?sel=649ec120b3856c10bcc2e779

Typo: Seperate the message string -> Split the message string

Fixed reference solution and added sample/fixed test for all 3 problematic chars.

ValueError: invalid literal for int() with base 10: '³3'

Is that normal I get weird chars in the input? (python ; random tests ; edit: got the error one time only, trying to reproduce in a fork, right now)

If so, this should be tested as fixed tests too (both sample tests and full test suite)

edit²: happens in bytes mode / the ref solution is failing in the very same way on this kind of inputs => the range should be limited, when creating the input

I actually just realized it's a problem of clarity of the description (which is pretty "opaque"...)

=> what's defining the alphanum mode it "only chars contained in the provided alphanumeric string/variable"

if the string only contains characters from the alphanumeric table, use the alphanumeric mode

Changed.

Otherwise if the string only contains alphanumeric chars, then encode it with the alphanumeric mode.

this is incorrect: whitespaces are converted with alphanum mode too while they aren't "alhpanumeric"
