I want to change the client language. I need a detailed guide. I have all the files and I want to change them from English to Korean. If I modify the localization.ini language, the letters are disappearing. If I succeed in changing the language, I want to make a detailed guide for beginners. I have a basic file. Please explain exactly which folder I need to put the file in and which file I need to modify. I've searched enough for a few days, but no one exactly tells me.
