How to find PDF documents without a specified language?

[Jensen Head]

Since the Language column in Windows File Explorer does not correspond to the same-name meta tag in PDF, it is currently difficult to find documents with a specific language, or without a specified language. At least with a large number of documents or with a large size.

Please consider adding this field to the PDF-XChange File Explorer add-on utility (PDF-XChange Shell Extensions), or adding a search parameter to the advanced document search (with the ability to search for a specific language in the list of languages ​​installed for a document or documents without an installed language).

Hello, Jensen Head

Thank you for the suggestion, I have passed this along to the Dev team for review, but as usual, I cannot make any promises until I have heard back from them.

[Edit]
At the very least, they are committed to investigating if this is possible, and we have a ticket for it now:

RT#7469: FR: shell ext - Add language metadata

Kind regards,

[Jensen Head]

Just keep in mind that the language can be specified not only in the Info dictionary (which is accessible via reader.metadata in PyPDF2), but also in the PDF (Root) catalog under the /Lang key (access via catalog = reader.trailer["/Root"]). As a separate script, this tool works, but for most users it would be convenient to use it via the GUI.
