Describe the bug
In UTF-8, many characters are one multiple bytes.
In the python app of the calculator, the len function count the number of bytes and not of characters.
Same for list, tuple and set functions : they create a list, tuple or set with all the bytes.

To Reproduce
If you enter :
a="éç"
list(a)
len(a)

It display :
["e","\u0301","c","\u0327"]
4

Expected behavior
Normally (and I try on Vscode to be sure), len just count the number of characters and not the number of bytes who composed them.
Same for list, tuple and set functions. Normally, you just have the characters inside, but not each byte splitted.

Screenshots
On the calculator:

On Vscode:
