What is Byte order mark (BOM)?
Byte order mark is the informal name of the special Unicode character encoding that appear as a magic number at the start of a text file or any other file types. Or consider it as representation for the UTF-8 BOM in ISO-8859-1.#

public_html/.htaccess: Invalid command ‘\xef\xbb\xb’, perhaps misspelled or defined by a module not included in the server configuration. Now your website may not work and it will show Error 500. Even if you are trying to edit the file in normal editor you wont be able to find out and remove those BOM.
