1- if the password/hash is made on -a US computer ill put the word pass123 in pass.txt encoded in UTF-8 ? correct ?
2- if  the password/hash "pass123"  is made on a russian computer with windows-1251 as default encoding ,should i put pass123 in a pass.txt encoded in windows-1251 ? correct ?  or i remain in utf-8 ?

UTF-8 uses one to four bytes to encode characters.
UTF-8 was designed for backward compatibility with ASCII
the first 128 characters are encoded using a single byte (8-bit) with the same binary value as ASCII

Windows-1251 uses one byte (8-bit) to encode characters.
the first 128 characters have the same binary value as ASCII

pass123 all these characters are ASCII

Thus, a file with these characters must be 7 bytes in size
regardless of whether it is saved in ASCII or UTF-8 or Windows-1251 format.

standard encoding for new files in np++ is UTF-8, you can change the encoding of the file to whatever you want

other widly used should be

plain ascii/ansi
windows-1252
iso-8859-1
iso-8859-15
