ASCII Usage of "\" about libnx HOT 2 CLOSED

First of all this is not libnx related, but GCC related.
Compiler is responsible for escape sequences

And it seems you don't know about escape sequences.

your code should look like this to properly render stickman

printf("\x1b[10;10H   O \n");
printf("\x1b[10;11H  /|\\ \n");
printf("\x1b[10;12H  / \\ \n");

from libnx.

Wikipedia has a brief explanation at https://en.wikipedia.org/wiki/Escape_sequences_in_C

from libnx.
