Reference: http://jybzjf.iteye.com/blog/2262392 Java read code has a BOM file before there is a bug, and later fixed.However, the addition of the files stream operation in JDK8 still does not seem to support BOM file reads. Read the file row data using the Files.lines, using the following method: Read all content list Can see JDK8 after using the files stream operation can only use a line of code, even wit

PHP realizes the automatic detection and removal of the BOM of UTF-8 files, This article describes the PHP to realize the UTF-8 file BOM automatic detection and removal method. Share it with you for your reference. The specific implementation method is as follows: BOM information is a hidden string starting with a file that is used by some editors to identify it

JAVA outputs a UTF-8 encoded file with BOMWhen the CSV file is output from the http response, it is not included by default when it is set to utf8.Bom, But windows Excel uses bom to confirm utf8 encoding, and all bom needs to be written to the beginning of the file.Microsoft uses BOM in UTF-8 because it can clearly dis

1. What is the BOM header?In a UTF-8 encoded file, the BOM occupies three bytes in the file header to identify the file as a UTF-8 encoded file. Currently, many software programs have recognized the BOM header, but some cannot recognize the BOM header, for example, PHP cannot recognize the

JS composition As we all know, javascript there are three components ECMAScript , DOM and, BOM depending on the host (browser), the specific manifestations are not the same, IE and other browser styles are different. 1. DOM is the standard of the web; [Standard for all browsers to comply]2. BOM is the various browser vendors according to DOMImplementation on the respective browsers; [behaves differe

I. Introduction UTF-8 is a Unicode character encoding method that is often used in web applications. The advantage of using UTF-8 is that it is a variable length encoding method, the length of the ANSII code is 1 byte. In this way, network bandwidth can be greatly reduced when a large number of ASCII character sets of webpages are transmitted.UTF-8 signature, also known as BOM (Byte Order Mark), is the standard tag used for identification encoding in

JAVAScriptThere are three parts, ECMAScript DOM and BOM , depending on the browser, the specific forms of expression are also different. Let's talk today about the differences between the DOM and the BOM.In terms of the encyclopedia:1. Dom is the standard of the "the"; [Standard of public compliance for all browsers]2. BOM is the implementation of various browser vendors according to the DOM in their respec

When the CSV file is output from HTTP response, it is set to UTF8 without the defaultBOM, but Windows Excel uses the BOM to confirm the UTF8 encoding, all need to write the BOM to the beginning of the file. Microsoft's use of the BOM in UTF-8 is due to the distinction between UTF-8 and ASCII encoding. Otherwise opening the CSV file with Excel may be garbled De

Tip: Users with UTF-8 encoding do not use Notepad to edit code files and template files, using tools that can remove the Unicode signature (BOM). If your website opens a blank, the style is lost, the program error is probably you use the tool that failed to remove the BOM to the template file or source code files have been modified. Now almost all text editing software can display and edit UTF-8 encoded f

Character encoding related information http://baike.baidu.com/view/1204863.htm UTF-8 encoded files can be divided into no BOM and BOM two kinds of formats. There is a BOM header storage or byte stream, it must be a Unicode character set encoding. The one that belongs to (Utf-8 or utf-16 or utf-32) can be judged by the head.

The bom header is actually a very hateful thing. Sometimes, due to the bom header, the page may be garbled, but sometimes it is necessary to add the bom header, next, let's take a look at how to automatically add the bom header when downloading a PHP file. I hope the article will be helpful to you. The
