Hi @mbhusty, thanks for submitting an issue, we'll look into this.

Hey, you need to use cyrillic recognizer instead of english one, so the initialization of the model should look like this:
const model = useOCR({ detectorSource: DETECTOR_CRAFT_800, recognizerSources: { recognizerLarge: RECOGNIZER_RU_CRNN_512, recognizerMedium: RECOGNIZER_RU_CRNN_256, recognizerSmall: RECOGNIZER_RU_CRNN_128, }, language: 'ru', });

Thnx! This is my fault

Maybe it is worth to highlight that fact in the documentation?

[mbhusty]

Yes, this point is not entirely clear in the documentation

Great idea, we will add a section about working with different languages.
