Description Matthias Clasen 2005-08-08 16:44:28 UTC 
It does not forget a seen BOM, therefore, you cannot reuse a UTF-16 -> UTF-8
converter for converting chunks of UTF-16 of different endianness, even if they
both start with a BOM.

The attached testcase demonstrates this.

Comment 2 Ulrich Drepper 2005-08-08 17:51:51 UTC 
This is not a bug.  Flushing using iconv() only resets the shift state.  This is
needed for stateful encodings with states where the caller wants a converted
string to end in the initial state.  The BOM recognition has nothing to do with
shift states.  Once the byte order is determined this is a property which stays
with the iconv_t descriptor for its lifetime.
