Can you give an example, how the runtime can not know the type of an
string?
If you just opened a file (no reading done yet) you don't know the
encoding.
Right, but it's still a file, not a string.
Or if the file has no BOM then you might want to guess the
encoding based on the content read. As long as you haven't guessed the
encoding (no matter whether the guess is right or wrong) you don't know
the encoding.
Right2. When no encoding is specified, Delphi reads (part of) the file
into a byte array and looks for a BOM (TEncoding.GetBufferEncoding). If
none is found, the preferred encoding (of the TStrings/TStream instance)
is used, or system encoding as the last resort.
