  1. thanks for helping - found also my mistake : after change from var LoadString: String; to var LoadString: AnsiString; code is working, with a typecast String(Loadstring) ; but now different issue .... this will now work for compiling under LINUX 😞
  2. I'm almost sure that I already used the code below without any issues in previous application. Now a added this to a new app and dumped the Loadstring variable into a memo with memo.lines.add ( Loadstring ) ; All text is now displayed using chines char's , the file I#m reading for sure is ASCII and only latin chars ..... What went wrong ? var LoadString: AnsiString; FS: TFileStream; begin FS := TFileStream.Create(FileName, fmOpenRead or fmShareDenyNone); try SetLength(LoadString, (FS.Size div SizeOf(Char))); if FS.Size > 0 then FS.Read(Pointer(LoadString)^, FS.Size); finally FS.Free ;
