The 154th UTC (Unicode Technical Committee) meeting, which starts one week from tomorrow, will have a very interesting agenda for me, based on the latest documents at the end of the 2017 document register, and in the 2018 one.
What is dearest to me are L2/17-436 and L2/18-013, which are two SVS (Standardized Variation Sequence) proposals that are effectively split versions of L2/17-056 that was discussed during UTC #153 last October. The feedback that I received was very useful. Why did I split the original proposal into separate ones? Quite simply, the SVSes in L2/17-436 are less controversial, and are more likely to be accepted. If accepted, these SVSes will be reflected in a future update of the Adobe-branded Source Han and Google-branded Noto CJK Pan-CJK typeface families.
Another SVS proposal that will be discussed is L2/18-020, which proposes an SVS for the historic horizontal form of U+3127 ㄧ BOPOMOFO LETTER I that looks like a vertical bar. If accepted, this SVS will also be reflected in a future update of the Adobe-branded Source Han and Google-branded Noto CJK Pan-CJK typeface families, though it is currently supported in those fonts via the OpenType 'hist' (Historical Forms) GSUB feature.
So, there are three CJK-related SVS proposals that will be discussed during UTC #154, which cover 52 characters and propose a total of 80 SVSes.
Also discussed during UTC #153 last October was L2/17-386, which proposed three new IDCs (Ideographic Description Characters), and the feedback led to L2/18-012, which is a revised proposal for four of them. The image below shows the current set of 12 IDCs, along with the four newly proposed ones that are highlighted in red:
My friend, Eduardo Marin Silva, resurrected an ancient proposal to encode characters in North Korea’s KPS 9566 standard by submitting L2/18-004. Feedback was submitted via L2/18-011, L2/18-014, and L2/18-017. I submitted my own feedback via the official contact form, which will be discussed during UTC #154.
