File -> Open in file window. Then you can choose file encoding. You can save it in the same way. I use Akelpad text editor for it.
ANSI is different, the main thing is that this first character is displayed and saved. I have ANSI (cyrillic). In the Junior’s tutorial, you can see that ANSI (latin) is used (“£ DILDO1”). It should work too.

1. Enable features in fastman92limitAdjuster_GTASA.ini
Enable melee combo type loader = 1
Max number of melee combos = 18
2. You need the melee.dat file. Check if you have it in your modloader, if so, take it as a base. This file is not combined in mods (there should be only one such file in the modloader). If you don't have it, then copy it from the data folder to modloader*your weapons folder*data.
Copy one of the combos in this file and paste it down. Rename the START_COMBO value to yours.
Change the values of the damage column to yours.
3. Go to gtasa_melee_config.dat, add line 17, etc. with your value name from melee.dat.
4. You need a weapon.dat file. Check if you have it in your modloader, if so, take it as a base. If you have several of them, then take the most relevant for you, or you can combine them into one. If you don't have it, then copy it from the data folder to modloader*your weapons folder*data.
Add the melee weapon lines from Loader.txt to the bottom of the Melee Weapons section. In Loader.txt, delete these lines.
Replace the numCombos value (for example BBALLBAT) with your value name from melee.dat.
