UTF byte order and BOM The byte order of the UTF-8UTF and BOM are encoded in bytes, there is no problem of the byte order. The UTF-16 uses two bytes as the encoding unit. before interpreting a UTF-16 text, you must first understand the byte order of each encoding unit. For example, if the Unicode encoding of "queue" is 594e and that of "B" is 4e59. If we receive the UTF-16 byte stream "594e", is this "Kui"

However, after writing a test UTF-8 XML file with UltraEdit, the program has an error reading the file:Parse Fatal Error at line 1 column 1: Content is not allowed in the preface. Org.xml.sax.SAXParseException:Content isn't allowed in Prolog ....Repeatedly checking the code can not be a problem, th

A text file created under Windows with a text editor that, if saved in Unicode format such as UTF-8, adds a BOM ID to the file header (the first character).This identifier is not removed when Java reads the file, and String.Trim () cannot be deleted. If you use ReadLine () to read the first line into a string, the length of the string is 1 larger than the one you see, and the first character is the BOM.This situation can cause some problems, such as w
