For example, 𘌇 and 𘟱 both correspond to LFW number of 5990, and are coded as 5990A and 5990B according to ccamc.co.
However, in Lines 174269 to 174283 in dictionary.js, the numbers are recorded as 90-A and 90-B. It seems that since the code in the original data is too long, only the last 4 characters in the code is considered, so that 59 at the beginning of the numbers are ignored.
