What’s different between UTF-8 and UTF-8 without a BOM? Which is better?
The UTF-8 BOM is a sequence of bytes at the start of a text stream (
0xEF, 0xBB, 0xBF) that allows the reader to more reliably guess a file as being encoded in UTF-8.
According to the Unicode standard, the BOM for UTF-8 files is not recommended:
2.6 Encoding Schemes
… Use of a BOM is neither required nor recommended for UTF-8, but may be encountered in contexts where UTF-8 data is converted from other encoding forms that use a BOM or where the BOM is used as a UTF-8 signature. See the “Byte Order Mark” subsection in Section 16.8, Specials, for more information.
