The specification for this is here: ftp://ftp.unicode.org/Public/UNIDATA/UnicodeData.txt

@adrianheine It appears that the beginning of the block also contains incorrect types when comparing our code to the specification above. For example, the first six items should be "AN", but we have "AL". Do you know if the other entries should be adjusted as well?

I don't know much about this. Since the first items are combining marks, I suppose their directionality doesn't matter too much?

I updated my commit to fix all 0600–06ff items, but feel free to favor your commit since it fixes all of them.

Closing as fixed in #7846. Thank you for bringing this to our attention!
