Special characters when uploading files

[mcurtaz]

If a string contains special characters, it will not be sent when uploading files using the uploadFiles method. This is an error that only occurs on Android.

RNFS.uploadFiles({
   toUrl: url,
   files: files,
   method: 'POST',
   headers: {
      'Accept': 'application/json',
   },
   fields: {
      "foo": "éùà'ç"
   }
})

I found this solution and it worked: solution

It might help someone, so I'll leave it here anyway.

Maybe this other pull request will work as well, but I haven't tested it yet: pull request.
