from the page:

{$codepage utf8}
const
   s1: shortstring = 'éà';
   s2: ansistring = #$094#$06D;
   s3: ansistring = #267#543;


In case of s2, s3 it's a do-able conversion, since the numeric values are already known.

But with s1 that could potentially be much much more work, and also very inconvenient for writing new code.
I would not know all the ordinal values from the top of my head, and if the string was long, it would mean to look up dozens of uni-codes.

It would be nice if there was(maybe there is) some way, of telling the compiler that the string is to be treaded as binary-data. Maybe like:

{$codepage utf8}
const
{$codepage binary} // temporary change
   s1: shortstring = 'éà';
{$codepage utf8} // back to original
  s2: ansistring = #$094#$06D;
  s3: ansistring = #267#543;
