Finally I’ve created an account here!
The font currently contains the following Compatibility Ideographs:
U+FA0C 兀 ngat6
U+FA0D 嗀 hok3
U+2F825 勇 jung5
U+2F83B 吆 jiu1
U+2F840 咢 ngok6
U+2F878 屮 cit3
U+2F894 弢 tou1
U+2F8A6 慈 ci4
U+2F8CD 晉 zeon3
U+2F994 芳 fong1
U+2F9B2 䕫 kwai4
U+2F9BC 蜨 sip3
U+2F9D4 貫 gun3
Their canonical forms (characters normalized to Unified Ideographs) are:
U+5140 兀
U+55C0 嗀
U+52C7 勇
U+5406 吆
U+54A2 咢
U+5C6E 屮
U+5F22 弢
U+6148 慈
U+6649 晉
U+82B3 芳
U+456B 䕫
U+8728 蜨
U+8CAB 貫
I wonder the compatibility characters should be removed from the font.
