[php-src] Issue #8308: The return value of mb_list_encodings() doesn't contain 'SJIS-win'

Issue: https://github.com/php/php-src/issues/8308 Comment Author: sj-i @alexdowad Ah, that point needs a little more context. To summarize, there is no direct relationship with the one-way mapping for this specific code point. Moriyama-san was working in several OSS communities at the time to make each OSS's character code processing interoperable with each other. There is a problem with practicality when a character that Japanese users generally regard as "the same" is changed to another character when converted via Unicode. He proposed the addition of several additional one-way mappings for the then-current ISO 2022 JP and EUC-JP encodings, as well as for ShiftJIS and its derivatives. Examples of such efforts can be found, for example, in the following URLs http://www.mysql.gr.jp/mysqlml/mysql/msg/12442 https://ja.osdn.net/projects/legacy-encoding/ Although not each of these efforts actually bore fruit, he chose to include ISO-2022-JP and EUC-JP in his mention of the topic because similar efforts were being made at the time for code points other than U+203E and U+00A5.
