1. Can VNRecognizeTextRequest return / identify results with extended alphabets? Letters like Ö, Ä, Å or ü.
- I've tested by setting Finnish to recognizedLanguages, but to no effect. It has not recognized the letters correctly.
2. It identify japanese, chinese and other asian character sets?
For a long time I wondered why my app does not recognize German umlauts (e.g. Ü ö ä or a ß) with VNRecognizeTextRequest.
Now I found out that umlauts are only recognized if I set :
.recognitionLevel= .fast and
.usesLanguageCorrection = false
Unfortunately, the .customWords seem not to work anymore and the quality of the text recognition is not good.
At this time, the VNRecognizeTextRequest only seems to support en-US.
VNRecognizeTextRequest.supportedRecognitionLanguages() always returns 1 value of en-US.
