Great!

Contain numbers that are not at the start of variables
Contain Chinese, Greek, Arabic characters, Ü, ß, Ç
Contain Unicode characters or emojis.
Start with zero-whitespace Unicode character, then numbers
Contain !, #, ^, &, *, (, ), =, +, /, , , . , :.
Start with a number
I made this Wiki so anyone can add.

So far, this is what I accomplished.
If I zoom in the character, I see this.
Nice. I tried.
However:
- if I delete all of the text in the variable name, it becomes this.
- if I delete all of the text except the white space, it becomes this.

This is what happens when I zoom in your blocks.
unicodes will work. There are some num digits as well! they are visual characters
that is a part of the unicode
and does the do it result say 5?
Possibly. I'm still trying.
My computer's font is Serif and your computer is Arial, so it does not support all devices. I would rather prefer Dora's one because it works both on my iPad and computer.
No matter what, we cannot start a variable with a number, we can only make a variable look like it starts with a number.
