Yes, I see Red Hat has a product enhancement for that, for coreutils,=20 dated 2019.[1] Shift-JIS is still very much alive and kicking in Japan in its own=20 circles. Even DBCS EBCDIC is still used among old mainframe=20 applications.[2] I very much doubt whether we need to worry about DBCS=20 EBCDIC in GNU software, though. Shift-JIS is a closer call as it's used a lot more than DBCS EBCDIC.=20 However, my worry is that good support for non-ASCII-safe encodings like=20 Shift-JIS is hard to do, and that any such support we'd add to=20 Gnulib/coreutils/etc. would not only increase maintenance costs and=20 reduce runtime performance, but also would be buggy in many oddball=20 corner cases (and this would have security implications).
