There are a few "commas" used in CJK which makes it complicated for me.
*FULLWIDTH COMMA U+FF0C* (link <https://www.compart.com/en/unicode/U+FF0C>) which might have the glyph in the center of the box or in the lower left corner depending on the font: [image: Screenshot 2023-10-18 at 17.19.27.png] [image: commaFullWidth.jpg] *HALFWIDTH IDEOGRAPHIC COMMA U+FF64* (link <https://www.compart.com/en/unicode/U+FF64>) which (as far as I can tell) will always be in the bottom corner regardless of font. (used to enumerate sequences) [image: Screenshot 2023-10-18 at 17.23.33.png] *COMMA U+002C*, (link <https://www.compart.com/en/unicode/U+002C>) which isn't part of formal CJK languages but in practice is used all the time [image: Screenshot 2023-10-18 at 17.21.50.png] So I'd like to train to recognize the three types of commas so the OCR output is matches the input images. "FULLWIDTH COMMA" is a problem because the glyph position in the box is different depending on the font. Hence my question "where and how big is the box?" [image: Screenshot 2023-10-18 at 17.28.40.png] In the image above, lines 1, 2, and 3 are all FULLWIDTH COMMA but line 1 is a different font. Line 4 is COMMA (U+002C) while line 5 is HALFWIDTH IDEOGRAPHIC COMMA U+FF64. What's the best way to train given those types of input and the expected output?
