It really depends on the compiler and its language. Some do, some
don't.

This is what many compilers do. In fact the intermediate
representation is pretty much ubiquitous.

In general both the compiler and the assembler need to know the
details of the target's object and code representations. So yes,
knowledge of instruction encodings, hexadecimal etc., are basic
requirements for a compiler or assembler author.
