A couple of weeks ago my sempai and I had a short discussion about kanji. He mentioned that he was looking into the differences between the two common ways of writing "ki," the one (as pictured on this website) with a cross with four marks at the corners under the "bar", or the one with the "x" under the "bar". He said that he was trying to find out if there were differences in connotation between the two. I always thought, since I primarily saw the "x" version on typing programs, and the "cross" version in handwritten calligraphy that the difference came because the cross was too hard to represent in a computer font, or the cross was an artistic embellishment for calligraphers.
Are there differences in meaning between the two?
