I cannot claim I understand these things. But I thought that there
was some kind of a "conversion formula" that allows one to calculate
the octal sequence for any utf-8 character and also the opposite,
get the character given the octal sequence. Is this true?

There is a little tool uni2ascii which seems to implement this, see


But if possible I would like to achieve this from within Emacs.
