This isn’t a major request, not one I’d ask over many others, but in future versions could be nice.
A lot of work I do, personal studying, is in Japanese. I know that DevonThink uses the Abby OCRing under the hood. Looking at primary and secondary languages, Japanese isn’t listed. As I mentioned, not a super high priority compared to other things, but since Abby already has pretty decent Japanese OCR (I pay for their FineReader product, and use the Japanese OCR often), it shouldn’t be too much to add in. So figured it’s worth bringing up.
On another side note, the menu and application isn’t in Japanese on a Japanese OS. Not a super big deal, and is something I can help with if there’s any desire to localize it to Japanese. Feel free to message me if you want help with that.
