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,
