extractThumbnail fails for images with special characters in the filename on Windows

It seems like extracting thumbnails from images with special characters in the name fails. I'm using the following code to extract the thumbnail from an image:

import { exiftool } from 'exiftool-vendored'
import * as path from 'path'

const file = './dummy_data/IMG_6176 - Cöpy.cr2'
const filePath = path.resolve(file)

async function extractThumbnail(file): Promise<void> {
  const outFile = file + '.thumbnail.jpg'
  console.log(`Extracting Thumbnail of ${file} -> ${outFile}`)
  return exiftool
    .extractThumbnail(file, file + '.thumbnail.jpg')
    .then(() => console.log('Thumbnail extracted'))
    .catch((error) => console.log('Thumbnail extraction failed:', error))
}

async function getExifTags(file): Promise<void> {
  return exiftool.read(file).then((tags) => {
    console.log(`Make: ${tags.Make}, Model: ${tags.Model}, Errors: ${tags.errors}`)
    console.log(`Description: ${tags.Description}`)
    console.log(`Keywords: ${tags.Keywords}`)
    console.log(`Rating: ${tags.Rating}`)
  })
}

async function main() {
  try {
    await getExifTags(filePath)
    await extractThumbnail(filePath)
  } finally {
    exiftool.end()
  }
}

main().then(() => console.log('Done!'))

And I'm getting the following Error:

Extracting Thumbnail of D:\Entwicklung\electron-vue-app\dummy_data\IMG_6176 - Cöpy.cr2 -> D:\Entwicklung\electron-vue-app\dummy_data\IMG_6176 - Cöpy.cr2.thumbnail.jpg
Thumbnail extraction failed: Error: File not found - D:/Entwicklung/electron-vue-app/dummy_data/IMG_6176 - Cöpy.cr2

    at BinaryExtractionTask._Task_resolve (D:\Entwicklung\electron-vue-app\node_modules\batch-cluster\src\Task.ts:144:38)

Note that reading the tags works as expected!

Bugfixes and tests are in new v19.0.0. Thanks for the bug report!

Thank you for the quick fix! I will try the new version!

Thanks for this! I was about to make a similar fix for another issue I don't see mentioned, which is that every write action that has been done before this was fixed introduced a mostly empty IPTC section. This is because CodedCharacterSet was specified which is an actual tag that exiftool is being told to set, not a modifier or configuration option like the others.

So now to go remove the IPTC section from all the files I've written in the past... 🤔
