I am coming here from CL https://go-review.googlesource.com/c/go/+/167781 created by @cuonglm's vigilance.
In particular it uses a wrong character for the 4th byte i.e.
0x20 " " for both RAR v5 and RAR v4 instead of 0x21 "!"
as per
Lines 188 to 189 in faa7fa0
The sniff signature that we got from the MIME sniff spec is wrong and that's acknowledged at
whatwg/mimesniff#63
but also the official RAR Labs website shows the correct signature as
