I tried to replace multiple CJK glyphs using the function of “Reencode Glyphs”. However, the unicode of those glyphs did not change and it didn’t work.
The version I used was the cutting edge version 2.5.2 (1176).
In addition, it works well with the stable version of 2.5.1 (1141).
I will send the .glyphs file so please tell me if there is a solution.
