Actual results:

Not all but some characters changed themselves into latin characters.


Expected results:

Since those latin characters are not included in the original documents, original characters or simple space should be showed there.

This is because our cid-to-unicode mapping table doesn't consider cids for hankaku-latin glyphs.

Hey! I also encountered such a problem in PDF files, but then some good people told me that this was due to the fact that the collation table was cid-to-unicode, as the commentator said above. Also, these people have their own service https://www.livepaperhelp.com/pay-for-paper.html for writing texts, abstracts and other types of essays, it helps students a lot. In this way I also learned the English language of the texts already started.
