[php-src] Issue #8281: mb_convert_encoding "\" (backslash) and "~" (tilde) convert failed to Shift_JIS

Issue: https://github.com/php/php-src/issues/8281 Comment Author: alexdowad Just did a brief search for Composer packages which might be affected by this issue. @SUKOHI's FluentCsv library uses SJIS-win, which is another name for CP932. (Good!) Likewise, @gh640's sjis-stream-filter library uses SJIS-win. However, @gh640 has another library called sjis-zip which uses SJIS (not SJIS-win). Also, @quyhoa has a library called Commoncsv which also uses SJIS. Comments from any of these developers on this GH issue would be much appreciated. Does anyone have a good way to do a text search across *all* Composer packages? I seem to remember that @nikic has, on occasion, mentioned that "the top 2000 Composer packages don't use such-and-such"; maybe he has something along those lines?
