Can Windows ocr recognize custom symbols/font?

I'm developing for UWP, Windows has an OCR engine: Windows.Media.Ocr

My question is: someone knows if the Windows OCR can be trained to recognize new characters or use a custom font? if yes, how i can do this?

what i want to achieve is to recognize non alphabetical symbols. I want to recognize per example the character ⌰ (unicode: U+2330) or ⌖ (U+2316).

The characters that i want to recognize are symbols not for any language.
