Report if a character is "printable".
Defined in <SDL3/SDL_stdinc.h>
int SDL_isprint(int x);
int | x | character value to check. |
(int) Returns non-zero if x falls within the character class, zero otherwise.
Be advised that "printable" has a definition that goes back to text terminals from the dawn of computing, making this a sort of special case function that is not suitable for Unicode (or most any) text management.
WARNING: Regardless of system locale, this will only treat ASCII values ' ' (0x20) through '~' (0x7E) as true.
It is safe to call this function from any thread.
This function is available since SDL 3.1.3.
