Characters added to script

I load a pas file from a Delphi project into the TIDEMemo and it generates an additional character in front of non-standard ASCII characters.

/// Single | Total floor area of the zone in m²
The character between the m and the super-script 2 has been added from nowhere.

Do you have steps to reproduce the problem? Can you provide the pas file and the code you use to load it?
Probably you are hitting some encoding issue.
