tab command for unicode characters

Some languages (Julia is one, there may be others) allow the user to write unicode characters via a tab completion command (i.e., you would write something like \alpha and then press the Tab key).

This works in jupyter notebooks, but not in JupyterLab as the Tab is reserved.

Is there a workaround?

Is there a list of the unicode chars that accept tab command? I see I can just input \ and tab to see a list, but what I actually would like is to know why there are certain codes and not others.

I try \nabla and it does not work. I first thought it was only the Julia symbols, but Julia accepts \nabla https://pkg.julialang.org/docs/julia/THl1k/1.1.1/manual/unicode-input.html

See, even if I just insert the unicode, ipython does not like it. File “<ipython-input-8-7f603a77904d>”, line 1 𝛁 = 3 ^ SyntaxError: invalid character in identifier

@fredguth Looks like “Python 3 restricts variable names to unicode characters that represent characters in written languages” (Ref).
