Huh, interesting. Did that really solve your problem for that specific PDF? (I wouldn't have thought that it's so easy 😅 ) |

Yes, the warning went away and the corresponding characters have been displayed, although I have not yet fully verified that the correct characters are emitted as this is hard for me as a non-Asian speaker. As already mentioned above and in the original issue report #2356, I have been surprised by this as well as I would have expected that we would already provide these simple mappings by default. |

Thanks! Please note that the next release might take a bit longer. I want to ensure that we do all breaking changes we want to do. It will be in January, but might be in the end of January. |
No worries. If this issue becomes too annoying in our monitoring in the meantime, I am sure that I manage to find a temporary solution ;) We/I just want to make sure that such issues have been properly analyzed and reported/fixed here before simply ignoring them. |
## What's new pypdf==4.0.0 is a big milestone forward: * We finally have a layout-mode text extraction. This enables users who want to detect / extract tables with heuristics to give it a try. * We deprecated a lot of the old PyPDF2 API that was either not following PEP8 naming styles or was not using a property. Users comming from PyPDF2 might want to switch first to pypdf<4.0.0 to get helpful error messages that show the new API in their speicific cases. A big 'Thank you!' the the whole pypdf community for your work. Thanks to you, pypdf is better than ever. Kudos to @shartzog who added the layout-mode with his first contribution! ### Deprecations (DEP) - Drop Python 3.6 support (#2369) by @MartinThoma - Remove deprecated code (#2367) by @MartinThoma - Remove deprecated XMP properties (#2386) by @stefan6419846 ### New Features (ENH) - Add "layout" mode for text extraction (#2388) by @shartzog - Add Jupyter Notebook integration for PdfReader (#2375) by @MartinThoma - Improve/rewrite PDF permission retrieval (#2400) by @stefan6419846 ### Bug Fixes (BUG) - PdfWriter.add_uri was setting the wrong type (#2406) by @pmiller66 - Add support for GBK2K cmaps (#2385) by @stefan6419846 ### Documentation (DOC) - Add pmiller66 for #2406 as a contributor by @MartinThoma - Add missing expand parameter (#2393) by @Atomnp - Resolve build warnings (#2380) by @stefan6419846 - Fix testing prerequisites (#2381) by @stefan6419846 - Improve formatting of contributors page (#2383) by @stefan6419846 - Add Tobeabellwether as a contributor for #2341 by @MartinThoma ### Developer Experience (DEV) - Make dependabot aware of our PR prefixes (#2415) by @stefan6419846 - Fail on Sphinx issues (#2405) by @stefan6419846 - Move title check to own workflow (#2384) by @MasterOdin - Write to temporary files instead of the working directory (#2379) by @stefan6419846 - Ensure that the PR titles have the correct format (#2378) by @stefan6419846 ### Maintenance (MAINT) - Complete FileSpecificationDictionaryEntries constants (#2416) by @MartinThoma - Return None instead of -1 when page is not attached (#2376) by @MartinThoma - Replace warning with logging.error (#2377) by @MartinThoma ### Testing (TST) - Add missing pytest.mark.samples annotations (#2412) by @kitterma - Correctly close temporary files (#2396) by @stefan6419846 - Fix side effect #2379 (#2395) by @pubpub-zz - Add test for layout extraction mode (#2390) by @MartinThoma ### Code Style (STY) - Use the UserAccessPermissions enum (#2398) by @MartinThoma - Run black (#2370) by @MartinThoma [Full Changelog](3.17.4...4.0.0)
This adds support for the GBK2K-H and GBK2K-V cmaps mentioned in #2356 where I stumbled upon directly.
I do not consider #2356 solved with this for now as it is not clear to me why we do not add the complete mapping once and how to get nice test data. For now, I unfortunately have private test data only.
