읫 or 욋?
Unihan database has “UYS” (읫, uys in Yale romanisation), but it is transcribed as 욋 (woys in Yale romanisation for pre-modern Korean) here and here (same text). (The entry 外叱怪面 in a list is probably a workaround for 夞怪面).
I cannot imagine any situation where uys would make sense.
Has 夞 been used for both woys and uys, or is this an error on the side of Unicode or whatever entity reported the character? Dustsucker 16:47, 17 February 2008 (UTC)
