.NET COBOL Strange behaviour when source file encoded to UTF-8 BOM

Hi,

When the source file (CBL) and any ancillary copybooks have been saved with an encoding of UTF-8 BOM then I am getting some strange behaviour with characters such as high-values when moving a PIC X group into a string and then moving it back out into a PIC X group.

My question is whether there a compiler option or some other mechanism whereby the source files are automatically converted to ASCII or UTF-8 at the time of building the dll?

Thanks
