Compiler Error CS2032
Response files and the command line options for csc.exe are not allowed to contain low-ASCII control characters in the range of 0-31, or the pipe (|) character. You cannot ordinarily generate this error directly from the command line because the command line processor filters out invalid characters, as does the integrated development environment (IDE). You can generate this error using a response file, as follows.
To generate this error
