We also find that the selection of the fonts by which variants (i.e. mainland Chinese, Taiwanese, Japanese, Korean) it was designed for is largely negligible, i.e. a Taiwanese font may score higher than a Japanese font, even though the latter features glyph variants closer to those found in our data. This is probably because the percentage of characters with regional variants is relatively small, and also implies that the characters’ stroke length and distance as well as small variations in the size of single character components is more relevant to the OCR accuracy when evaluating on real-life character images.
