No, byte-to-position already checks for that:
---- src/marker.c, line 302
/* If this buffer has as many characters as bytes,
each character must be one byte.
This takes care of the case where enable-multibyte-characters is nil. */
if (best_above == best_above_byte)
return bytepos;
----
Therefore, an Info file in Latin-1 should work just fine.

I think you mean UTF-32 instead of UTF-16, since UTF-16 is variable-
length.
