I want it to be utf-8, but it isn't.  The course of events is apparently
that when a new buffer gets created it will have the default coding
system.  You are then apparently asking that buffer for the coding
system (always the default) and set inputenc accordingly, but should
have asked the parent Org buffer.  Or so I think, a few details are
probably still wrong.

Both.

No it is not irrelevant, it simply gets set too late in the game: it
asks for the new coding system when it is time to save the buffer, while
the content of the buffer has been cobbled together while assuming a
different coding system.  The only way I know (from browsing the
documentation) to override the coding system for a buffer that does not
yet have a file association is to set that variable directly,
preferrably directly after the buffer is created.
