Syntax

BOMFILE | NOBOMFILE

BOMFILE: Specifies to write a byte order mark (BOM) prefix when a Unicode-encoded file is written to an external file.
NOBOMFILE: Specifies not to write a BOM prefix when a Unicode-encoded file is written to an external file.

The BOMFILE system option does not apply when a Unicode-encoded external file is read.

A BOM is a signature at the beginning of a Unicode data stream. The size of the BOM varies depending on the encoding.
