Trouble With Binary String In Javascript Above Character Code 128

So I'm trying to create and save a binary file locally in javascript using this library: https://github.com/eligrey/FileSaver.js/ It is a bit tricky because I am using GameMaker st

Solution 1:

Instead of using a String, you'd probably be better off using a Uint8Array (meaning an array of unsigned bytes in the range 0–255); see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array. For example:

ildablob[argument0] = new Uint8Array(1);
ildablob[argument0][0] = argument1;

...

var blob = new Blob(ildablob, {type: "application/octet-stream"});

Also, incidentally — argument0 and argument1 are terrible variable-names. You mention that you're constrained by GameMaker; is that the reason for this? It seems like there should be some way to fix that.
