Change Radical to 108.0 (皿) or add it as the secondary one, SC=15, FS=3

The semantic element is 盘, and the phonetic element is 音. 音 reads as ʔɤm¹ and ʔom¹

The IRG needs to have an intelligble policy on assignment of radicals. We originally based it on semantic, then the policy seems to have switched to "most intuitive". 180 is "intuitive"; 108 is semantic. Which is it to be?

For Comment #10021, understand Lee’s comment. In IRG N2412R, the authors pointed out this issue, and IRG discussed it during IRG #53 in Shenzhen. The following is the recommendation IRG M53.6.


In the subsequent actual operation in our review works, we include two kinds of radicals. We may have the following possibilities, and we can choose one of them.
(1) The intuitive radical is the primary one, the semantic radical is the secondary one.
(2) The semantic radical is the primary one, the intuitive radical is the secondary one.

To respond to Comments #10021 and #10022, which I just saw because this is the first time for me to review this portion of the working set, we are not building a formal dictionary, but rather establishing incremental repertoires of Han ideographs that now include over 100,000 such characters. Given that Han ideographs are found in various regions, and that many are unique to a given region, when searching for Han ideograph, it is often unclear as to which component serves which function. This is why I would advocate that the most intuitive radical, regardless of whether it serves as the semantic component or not, should be the primary one. It is also important to add a secondary radical when doing so would aid in discoverability. Perhaps the best ways to search for an ideograph is by using the Radical-Stroke Index that the Unicode Consortium includes with each version of the Unicode Standard, as an interactive web page, as a PDF file that is for visual searching (RSIndex.pdf), and now as a plain-text data file that can be used to programmatically search (RSIndex.txt).

Remove the secondary radical.
