DriveApp：搜索具有非拉丁名称的文件夹

Question

I ran into what seems to be an issue inside 'getFoldersByName()' method of the Folder class. If I pass a Cyrillic string as an argument, it returns the instance of FolderIterator as it should, but calling the 'next()' method always throws an error ('iterator has reached the end').

The function below finds the subfolder with a given name inside the parent folder and returns the subfolder. If the subfolder already exists, the function returns it instead of creating a new one. Unfortunately, this only works with Latin subfolder names.

function findSubfolder(){

  var subfolderName = "Папка папка";  //string containing cyrillic characters

  var parentFolder = DriveApp.getFolderById(parentFolderId);

  var iterator = parentFolder.getFoldersByName(subfolderName);

  var folder = (iterator.hasNext()) ? iterator.next() : parentFolder.createFolder(subfolderName);

return folder;

}

It's worth mentioning that when I check (existingSubfolder.getName() == subfolderName) it returns 'true'.

I'm not sure whether this is useful for your situation. So please think of this as one of several answers. In my environment, I also had the situation like you. In my case, it occurs for getFilesByName() . Ref I solved the situation by using searchFiles() instead of getFilesByName() . So I thought that this way might be able to be used for your situation. The modified script is as follows. It uses searchFolders() instead of getFoldersByName() as a workaround.

function findSubfolder(){
  var subfolderName = "Папка папка";  //string containing cyrillic characters
  var parentFolder = DriveApp.getFolderById(parentFolderId);
  var iterator = parentFolder.searchFolders("title contains '" + subfolderName + "'"); // Modified
  var folder = (iterator.hasNext()) ? iterator.next() : parentFolder.createFolder(subfolderName);
  return folder;
}

If I misunderstand your question and this is not useful for you, I'm sorry.
