umlaut in directory path throws error #406
Description
using a path with umlauts (ä,ü,ö) for the directory argument of openStore throws an error. It attempts to create a different directory / umlauts are replaced with other characters.
Why is this relevant?
The application support directory includes the user name. The user name in Windows can include umlauts. The application support directory is the prefered location for such files, i.e. databases like objectbox. Other directories often include the user directory as a part. Therefore, this issue is quite a severe one for Windows support.
Basic info (please complete the following information):
- ObjectBox version: 1.4.1
- Flutter/Dart SDK:
Flutter 2.10.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision db747aa133 (8 weeks ago) • 2022-02-09 13:57:35 -0600
Engine • revision ab46186b24
Tools • Dart 2.16.1 • DevTools 2.9.2
- Null-safety enabled: yes
- Reproducibility: always
- OS: Windows 10
Steps to reproduce
final sep = Platform.pathSeparator;
final appSupportDir = await getApplicationSupportDirectory();
final dirPath = '${appSupportDir.absolute.path}${sep}testäüö${sep}objectbox';
await Directory(dirPath).create(recursive: true);
_store = await openStore(
directory: dirPath,
);Expected behavior
- if not already existent, create the directory
.../testäüö/objectbox - create store / save store to this directory
