Why exactly are you trying to use a BIP39 seed phrase as an Electrum seed phrase? You are adding unnecessary confusion. Electrum checks that any seed phrases it generates aren't accidentally also valid BIP39 seed phrases, and discards them if they are.
because I'm not a programmer.
And no one will write a complete program for generating a new version of the seed to me on the forum.
I have a BIP39. everything works.
It just needs to be filtered. It should be easy.)
from this python example I took the line
seed = u''.join([seed for i in range(len(seed)) if not (seed in string. whitespace and is_CJK(seed[i-1]) and is_CJK(seed[i +1])))])
as far as I understand - they just remove all(?) spaces.
but still can't filter
hope someone in java can help me
