Hi @123244 thank you for reaching out on Microsoft Q&A!
I'm sorry Ukrainian is not a support language.
The Windows OCR engine supports 25 languages, including Chinese (Simplified and Traditional), Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian (Cyrillic and Latin), Slovak, Spanish, Swedish, and Turki - and unfortunately, Ukrainian is not included.
You can also retrieve the list of language that supported by run this command in PowerShell as Administrator:
Get-WindowsCapability -Online | Where-Object { $_.Name -Like 'Language.OCR*' }
However, you can use Azure AI Vision, a cloud-based OCR, as an alternative. This document provide the list of language that supports, including Ukrainian. You can learn more here.
I hope this helps you get things back on track quickly! If my suggestions can solve your issue, feel free to interact with the system accordingly!
Thank you!
