Hello,
So is escaping single quotes still necessary?
It is necessary inside a char literal to distinguish the content of the literal from its enclosing single quote signs. Inside a string literal it is not necessary. Assuming the EXCEL file contains strings only, escaping single quotes can be ignored.
Is it possible to invoke EW (or Chorac?) via command line and tell him "hey, read the strings.ewu file and regenerate it"?
No, this is not possible. I would recommend to adapt the EXCEL conversion so that its outputs are better comparable with the original EWU syntax.
Best regards
