Steven Rowe commented on LUCENE-1157:
-------------------------------------
bq. there are unidentifiable characters in Changes.html. They are also in
CHANGES.txt. I'm sure I read something about why they are added but cannot find
it now.
The first three bytes of CHANGES.txt are a UTF-8 BOM (byte-order mark). In
Unicode's fixed-width encodings, e.g. UTF-16, the character U+FEFF is reserved
for the beginnings of streams to denote the endian-ness of the character
serialization.
UTF-8 is non-endian (invariant byte order given a character); the use of the
BOM in UTF-8, where it is serialized as three bytes, is solely to indicate that
the encoding of the stream is UTF-8.
Microsoft's tools like to put BOMs at the beginnings of UTF-8 encoded files.
