git.add adds wrong filepath when filepath is multibyte string (like Japanese)

I encountered on Node@10, Chrome 68 and isomorphic-git@0.24.2

  const root = '/my-root'
  const addingFilepath = "日本語"
  await fs.promises.writeFile(path.join(root, addingFilepath), "1")
  await git.add({ fs, dir: root, filepath: addingFilepath })
  await git.commit({
    fs,
    dir: root,
    message: "Add japanese file",
    author: { email: "dummy", name: "dummy" }
  })
  const files = await git.listFiles({ fs, dir: root })
  console.log(files)

This result lost some data

 [ '日' ] // expected:  ['日本語']

Thank you! It works in this case!

but … sorry, now I found another case under directory.

  const addingFilepath = "docs/日本語"
  await fs.promises.writeFile(path.join(root, addingFilepath), "1")
  await git.add({ fs, dir: root, filepath: addingFilepath })
  await git.commit({
    fs,
    dir: root,
    message: "Add japanese file",
    author: { email: "a", name: "a" }
  })
  const files = await git.listFiles({ fs, dir: root })
  console.log(files) // [ 'docs/日' ]

Ah yes. It’s not because it was under a directory per se, but due to the length of the filename. Thank you for the fix!
