From an App Store review:

please add chinese-gbk-dos coding system

please add chinese-gbk-dos coding system, or any file with Chinese characters will not assign correctly

Chinese characters work fine if the file is encoded with UTF-8, but it would still be better to be able to handle a variety of encodings.

Also *-dos files should be handled correctly already.

I've added encoding auto-detection in v1.12.0. Test builds for Android and iOS are available.

Note, however that the requested GBK is currently only supported on iOS. On Android, support may be coming soon; as soon as it is available I will update Orgro.

@amake Could you please test if this file works fine on iOS? The update has not been shown on the app store. Thanks very much.

I have not released the new version yet; it is available for testing via TestFlight from the link I mentioned above.

Here is a screenshot of the result for the file you supplied:

Please note that the auto-detection is heuristic-based; if the Chinese text doesn't occur until later in the file it might not be detected correctly.

Thanks for the prompt reply. That is perfect! All characters and auto detections works well.

Thanks for confirmation. I'll submit 1.12.0 for release then.

══╡ EXCEPTION CAUGHT BY SCHEDULER LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during a scheduler callback:
Layer OffsetEngineLayer was previously used as oldLayer.
Once a layer is used as oldLayer, it may not be used again. Instead, after calling one of the
SceneBuilder.push* methods and passing an oldLayer to it, use the layer returned by the method as
oldLayer in subsequent frames.
'dart:ui/compositing.dart':
Failed assertion: line 110 pos 9: '<optimized out>'

Either the assertion indicates an error in the framework itself, or we should provide substantially
more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
