@Kwakx can you confirm the license for the content?
According to the information in the link provided, it seems the files has several licenses and some of them are very much different from the one which PaddleOCR is using. Please clarify if I miss-understood it.

I asked them via email because the number of licenses can be confusing.

Response:
"We confirm that the license is selectable"

So it can be used under the Apache 2.0 license, the same as PaddleOCR.
