 Known Issues
 ============
 
--  Reading order is based on the model’s sorting of text distribution in
-   space, which may become disordered under extremely complex layouts.
+-  Reading order is determined by the model based on the spatial
+   distribution of readable content, and may be out of order in some
+   areas under extremely complex layouts.
 -  Vertical text is not supported.
--  Tables of contents and lists are recognized through rules; a few
-   uncommon list formats may not be identified.
--  Only one level of headings is supported; hierarchical heading levels
-   are currently not supported.
+-  Tables of contents and lists are recognized through rules, and some
+   uncommon list formats may not be recognized.
+-  Only one level of headings is supported; hierarchical headings are
+   not currently supported.
 -  Code blocks are not yet supported in the layout model.
--  Comic books, art books, elementary school textbooks, and exercise
-   books are not well-parsed yet
--  Enabling OCR may produce better results in PDFs with a high density
-   of formulas
--  If you are processing PDFs with a large number of formulas, it is
-   strongly recommended to enable the OCR function. When using PyMuPDF
-   to extract text, overlapping text lines can occur, leading to
-   inaccurate formula insertion positions.
+-  Comic books, art albums, primary school textbooks, and exercises
+   cannot be parsed well.
+-  Table recognition may result in row/column recognition errors in
+   complex tables.
+-  OCR recognition may produce inaccurate characters in PDFs of
+   lesser-known languages (e.g., diacritical marks in Latin script,
+   easily confused characters in Arabic script).
+-  Some formulas may not render correctly in Markdown.
