Coding systems is not relevant in `insert'.

There are two ways to convert unibyte string to multibyte;
string-make-multibyte and string-as-multibyte .  Emacs'
default behaviour for converting unibyte to multibyte
(including the case of `insert') is by
string-make-multibyte.  But, if one want to preserve the
original bytes, he must use string-as-multibyte.
