The dominant baseline should be alphabetic, so the 'a' will be sitting on the blue line, the Japanese character '犜' will be on the ideographic baseline and 'ण' is a Devangari character and will use the hanging baseline. The smaller versions of the characters should be aligned to the same baselines. So the 'a's on the blue line, the Japanese characters slightly below the line and the Devangari characters should be hanging from the hanging baseline.
