A cast to unsigned char doesn't actually do anything. Every char is "representable" as an unsigned char because it holds a bit pattern between 0x00 and 0xff i.e. the function is well defined if the incoming int is either EOF (int -1) or else in the range 0x00 to 0xff. But I did a bit of searching and it seems it comes down to potential arithmetic operations on the "char" the might behave differently depending on the signed-ness. :( ------------- PR Comment: https://git.openjdk.org/jdk/pull/19567#issuecomment-2157677944
