Issue with spanish special characters
If you are using the default font that seems Roboto-Regular.ttf and you try to put "áéíóú", you can see a bug with capital letters instead of normal letters.
I attach an example On the bottom is the code, and on the top (with background) is on the program.
It is obtained ussing the function "write_string(0,400, 585, 1, &str);" in my case.
