Hi yancharkin, how are you?
My name is Gabriel and I'm from Brazil. I am a freelance translator and I am also finishing a Bachelor's degree in Translation at the Federal University of Uberlândia. In the monograph that I will write as a requirement to complete the course, I intend to translate a game into Brazilian Portuguese and describe/analyze the whole process. I was very interested in your work and would like to contribute to the translation of Spelunky Classic HD into my native language.
I started the whole process that you described in the tutorial, but I immediately noticed a problem that I will have. The special Portuguese characters (Á, É, Ê á, é, Ê, etc.) cannot be viewed within the game. These characters disappear entirely if I use the base English files. Is this what you described in Step 2? I need all of these: ÁÂÀÃÉÊÍÓÔÕÚ. I have no idea how I'm going to draw the additional characters and make this work. I also do not know Python to use the other method you mentioned.
I am using the windows version files that you made available on itch.io.
