getUnicodeSetImpl

void getUnicodeSetImpl(UnicodeSet setFillIn,
 int which)

Description copied from class: CharsetICU

This follows ucnv.c method ucnv_detectUnicodeSignature() to detect the start of the stream for example U+FEFF (the Unicode BOM/signature character) that can be ignored. Detects Unicode signature byte sequences at the start of the byte stream and returns number of bytes of the BOM of the indicated Unicode charset. 0 is returned when no Unicode signature is recognized.
