Opt Subject: PRI #374 (Proposed Update UTS #39) Feedback
In Section 5.4, "Optional Detection," item 3.b needs to be reconsidered, mainly because I am not aware of a Unihan Database (aka UAX #38) property that indicates whether a particular ideograph *is* simplified or traditional, but there are properties that indicate whether a particular ideograph *has* a simplified or traditional counterpart, and what its code point is. A prototypical example involves U+56FD 国 versus U+570B 國. The former specifies, via its kTraditionalVariant property value, that the latter is its traditional counterpart, and the latter specifies, via its kSimplifiedVariant property value, that the former is its simplified counterpart: U+56FD kTraditionalVariant U+570B U+570B kSimplifiedVariant U+56FD U+53F0 台 is an exception in that it is considered both a simplified and traditional form, and in addition to itself, it has three additional traditional forms, U+6AAF 檯, U+81FA 臺 & U+98B1 颱: U+53F0 kSimplifiedVariant U+53F0 U+53F0 kTraditionalVariant U+53F0 U+6AAF U+81FA U+98B1 In other words, a more accurate statement, which accounts for the vast majority of simplified/traditional pairs, is as follows: "Testing for whether a character is S or T can be based on whether the character has an S or T variant."
