And I think it's ugly and hackish to call Lisp from within C code,
when all that Lisp does is simple integer arithmetics.

IIRC, `decode-char' was originally coded in Lisp because it was added
at the last moment before some past release happened.  That was cool
as long as it was a rarely-used vehicle for converting Unicode
codepoints to the Emacs internal representation, but it's certainly
NOT cool, IMO, as part of the Lisp reader.

??? inside the Lisp reader, everything needs to be fast, IMO.

Which will be when? 5 years from now?
