All files are named in a consistent format to ensure easy indexing and association between images and their corresponding annotations: JPEG images are named 'image_<number>.jpg' (e.g., 'image_1.jpg'), and TXT files are named 'gt_image_<number>.txt' (e.g., 'gt_image_1.txt').

In these TXT files, annotations of Dongba characters include a verified total of 111,702 characters, ensuring the accuracy and reliability of the data. Each character's spatial position is identified by a series of coordinate pairs that define the polygonal boundaries of the text boxes. For example, the coordinate sequence "161, 59, 202, 57, 256, 85, 239, 154, 182, 147, 163, 107" represents the vertices of a polygon, with each pair like "161, 59" indicating the x and y coordinates of a vertex.
