I did the encode and it did remove the null character but I see that as a serious concern. How then, can one draw font without those characters in a cross platform way? Also it did kinda seem that playing with the encoding of the test made the color application not stick to the font consistently

Now just to figure out how to draw a rect in SDL and copy the texture to it so its predictable

Okay so this

renderSolid(text: string, color: Color) {
        try {
            const encoder = new TextEncoder()
            const buffer = encoder.encode(text);
            const raw = sdl2Font.symbols.TTF_RenderText_Solid(
                this[_raw],
                buffer,
                color[_raw],
            );
            return new Texture(raw);
        } catch (error) {
            console.log("error", error)
        }
    }

renderSolid(text: string, color: Color) {
        try {
            const encoder = new TextEncoder()
            const buffer = encoder.encode(text);
            const raw = sdl2Font.symbols.TTF_RenderText_Solid(
                this[_raw],
                buffer,
                color[_raw],
            );
            return new Texture(raw);
        } catch (error) {
            console.log("error", error)
        }
    }

with

"TTF_RenderText_Solid": {
        "parameters": ["pointer", "buffer", "pointer"],
        "result": "pointer",
    },

"TTF_RenderText_Solid": {
        "parameters": ["pointer", "buffer", "pointer"],
        "result": "pointer",
    },

is acceptable and doesn't error out

I've changed every value in here to null and identified the text as the problem it seems

const raw = sdl2Font.symbols.TTF_RenderText_Solid(
  this[_raw],
  null, // asCString(text)
  color[_raw],
);

const raw = sdl2Font.symbols.TTF_RenderText_Solid(
  this[_raw],
  null, // asCString(text)
  color[_raw],
);

This will atleast not result in an error

Tried casting color and the pointer to BigInt and tried using TextEncoder but no change https://stackoverflow.com/questions/61813646/whats-deno-equivalent-of-node-js-buffer-fromstring

Could be either the this[_raw] or the Color since that might be being passed in as a pointer. Casting both using the asCString did not fix, nor did changing the type expectations in the relevant section

I tried to cast it as an array buffer but it said allocation failed

renderSolid(text: string, color: Color) {
        try {
            console.log("text", text, "color", color)
            console.log(
                "this[_raw]", this[_raw],
                "asCString(text)", asCString(text),
                "color[_raw]", color[_raw],
            )
            const pointer = this[_raw];
            const buffer = new ArrayBuffer(pointer);
            const raw = sdl2Font.symbols.TTF_RenderText_Solid(
                buffer,
                asCString(text),
                color[_raw],
            );
            return new Texture(raw);
        } catch (error) {
            console.log("error", error)
        }
    }

renderSolid(text: string, color: Color) {
        try {
            console.log("text", text, "color", color)
            console.log(
                "this[_raw]", this[_raw],
                "asCString(text)", asCString(text),
                "color[_raw]", color[_raw],
            )
            const pointer = this[_raw];
            const buffer = new ArrayBuffer(pointer);
            const raw = sdl2Font.symbols.TTF_RenderText_Solid(
                buffer,
                asCString(text),
                color[_raw],
            );
            return new Texture(raw);
        } catch (error) {
            console.log("error", error)
        }
    }

Error

Must be the this[_raw] since thats a Deno.UnsafePointer
