It seems like I managed to make a mask, I created an md5 password for the test with 3 characters דהו, but no matter what encoding I convert to, only UTF 8 finds the password, but not as 3 characters, but as 6.
tell me how to solve? after all, if the password is 8 characters, then there is no way I can guess a password of 16 characters using the mask, there is not enough power

this is a common misunderstanding when it comes to utf-8 or any other multibyte charset

hashcat works on bytesized objects, so any of your utf-8 chars like א is in fact 2-bytes long, thats why hashcat needs more "characters" to find that char, UTF-8  א is in hex representation D7 90, so 2 bytes, 3 human chars = 6 "hahscat-chars"

codepage for hebrew is 862 BUT you have to be sure that, the passwort or hashingtask was done/encoded with this specific codepage BUT in as you see in your own example, standard encoding on pc's is UTF-8

so bruteforcing multibyte chars yeah is quite not really "nice" task
