Availability:C-language interface function

int ScheckBOM(IOSTREAM *s)

This function may be called on a buffered input stream immediately after opening the stream. If the stream starts with a known Byte Order Mark (BOM) the encoding is set accordingly and the flag SIO_BOM is set on the stream. Possibly resulting encodings are ENC_UTF8, ENC_UNICODE_BE and ENC_UNICODE_LE.
