readStream error with utf8 file containing arabic

[alainib]

When i write arabic content and try to read them i get this error :

  readStream error Error: Failed to convert data to utf8 encoded string. This might be because this encoding cannot be used for this data.

both call are made with 'utf8' param

export async function writeStream(path, content, encoding = "utf8") {
  return new Promise(function(resolve, reject) {
	RNFetchBlob.fs.writeFile(path, "", encoding).then(res => {
	  RNFetchBlob.fs.writeStream(path, encoding).then(ofstream => {
		ofstream.write(content);
		ofstream.close();
		return resolve(true);
	  });
	});
  });
}


export async function readStream(path, encoding = "utf8") {
  let data = "";

  return new Promise(function(resolve, reject) {
	RNFetchBlob.fs.readStream(path, encoding, 102400).then(ifstream => {
	  ifstream.open();
	  ifstream.onData(chunk => {
		data += chunk;
	  });
	  ifstream.onError(err => {
		console.warn("readStream error", err);
		return resolve(false);
	  });
	  ifstream.onEnd(() => {
		return resolve(data);
	  });
	});
  });
}

Version :
"rn-fetch-blob": {
"version": "0.10.15",
"resolved": "https://registry.npmjs.org/rn-fetch-blob/-/rn-fetch-blob-0.10.15.tgz",
}

Any tips ?
