Bug feedback: When using the paddle version of umiocr 2.1.5, the position of the editable text in the double-layer searchable and single-layer plain text PDFs generated when identifying traditional Chinese vertical PDFs is incorrect, and many texts are overlapped in the single-layer plain text PDF.
