Extended alphabets in TextRecognition

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?

Hi masterblaster,


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.


Cheers,

Michael

In iOS 14, the language support has been improved.

The .fast pass can now recognize: ["en-US", "fr-FR", "it-IT", "de-DE", "es-ES", "pt-BR"]

The accurate pass can also read chinese. ["en-US", "fr-FR", "it-IT", "de-DE", "es-ES", "pt-BR", "zh-Hans", "zh-Hant"]
