Problem with encoding when returning buffer instead of output file about node-poppler

[Fdawgs]

Thanks for reporting this @mcdado!

I'll look at removing the default encoding.

@mcdado, I've removed this in v3.0.1 😁

Thanks for removing that!

However, I still can't get a valid conversion from the stdout back into a binary format.

const pdfBuffer = await fs.promises.readFile(inputPdfFile)
const result = await poppler.pdfToCairo(pdfBuffer, null, { singleFile: true, pngFile: true }) // jpg too!
const pngBuffer = Buffer.from(result);
// const pngBuffer = Buffer.from(result, 'utf-8'); // also tried this
// const pngBuffer = Buffer.from(result, 'binary'); // also tried this
// const pngBuffer = result; // also tried this
await fs.promises.writeFile(outputPath, pngBuffer); // always a broken file.

Am I missing something obvious?
@mcdado, could you share a snippet of your final working code?
And thanks for this library, @Fdawgs !

@cepm-nate, what version of the module are you using, and with what OS?

[cepm-nate]

Node-Poppler 5.0.2, running on Node on Windows Server 2019. Can I get you any other info that might help? It's a head-scratcher for me.

I'll take a look tomorrow @cepm-nate, if you can share the pdf as well that'd be fab!
