Delphi Compiler Error

E2038 Illegal character in input file – ‘%s’ (%s)

Reason for the Error & Solution

The compiler found a character that is illegal in Delphi programs.

This error message is caused most often by errors with string constants or comments.

program Produce;

begin
  Writeln("Hello world!");   (*<-- Error messages here*)
end.

Here a programmer fell back to C++ habits and quoted a string with double quotes.

program Solve;

begin
  Writeln('Hello world!');   (*Need single quotes in Delphi*)
end.

The solution is to use single quotes. In general, you need to delete the illegal character.
