When I read the file using Java, it reads the BOM characters too. So I want to save this file in UTF-8 format without appending a BOM initially in Notepad. Otherwise is there any built-in class in Java that eliminates the BOM characters that present at beginning, when reading the contents in a file? 回答1: Use Notepad++ - free and much better than Notepad. It will help to save text without BOM using Enconding > Encode in UTF-8 without BOM : When I

I trying to remove BOM from string in this way: out.write(l.replace('\uFEFF','\0') + "\n"); But it don't work. Why? Output of this string in win-1251 file: ?1,...SOME_TEXT_HERE First "?" sign is illegal. 回答1: You're replacing the BOM with U+0000, rather than with an empty string. You should replace the BOM with the empty string, e.g. out.write(l.replace("\uFEFF", "") + "\n"); 文章来源: Remove BOM from string in Java

Now script is working great, except that there is no BOM. 回答1: Write it directly at the beginning of the file: file_new . write ( '\ufeff' ) 回答2: It's better to use constants from 'codecs' module. import codecs f . write ( codecs . BOM_UTF16_LE ) 回答3: Why

The utf-8 conversion works but BOM is still there. How would I remove this? This is what I currently have: batch_3={'src':'/Users/jt/src','dest':'/Users/jt/dest/'} batches=[batch_3] for b in batches: s_files=os.listdir(b['src']) for file_name in s_files: ff_name = os.path.join(b['src'], file_name) if (os.path.isfile(ff_name) and ff_name.endswith('.json')): print ff_name target_file_name=os.path.join(b['dest'], file_name) BLOCKSIZE =

But i would like a very precise way to find a files Encoding. So precise as Notepad++ is. 回答1: The StreamReader.CurrentEncoding property rarely returns the correct text file encoding for me. I've had greater success determining a file's endianness, by analyzing its byte order mark (BOM): /// /// Determines a text file's encoding by analyzing its byte order mark (BOM). /// Defaults to ASCII when detection of the text file's endianness fails.

I know that all of my JSON files are encoded in UTF-8, but the data entry person who edited the JSON files saved it as UTF-8 with the BOM. When I run my Ruby scripts to parse the JSON, it is failing with an error. I don't want to manually open 58+ JSON files and convert to UTF-8 without the BOM. 回答1: With ruby >= 1.9.2 you can use the mode r:bom|utf-8 This should work (I haven't test it in combination with json): json = nil #define the variable outside the block to keep the data

ǰϷ 到目前为止，我们已经学过了JavaScript的一些简单的语法。但是这些简单的语法，并没有和浏览器有任何交互。 也就是我们还不能制作一些我们经常看到的网页的一些交互，我们需要继续学习BOM和DOM相关知识。 JavaScript分为 ECMAScript，DOM，BOM。 BOM（Browser Object Model）是指浏览器对象模型，它使 JavaScript 有能力与浏览器进行“对话”。 DOM （Document Object Model）是指文档对象模型，通过它，可以访问HTML文档的所有元素。 Window对象是客户端JavaScript最高层对象之一，由于window对象是其它大部分对象的共同祖先，在调用window对象的方法和属性时，可以省略window对象的引用。例如：window.document.write()可以简写成：document.write()。 window对象 所有浏览器都支持 window 对象。它表示浏览器窗口。 *如果文档包含框架（frame 或 iframe 标签），浏览器会为 HTML 文档创建一个 window 对象，并为每个框架创建一个额外的 window 对象。 *没有应用于 window 对象的公开标准，不过所有浏览器都支持该对象。 所有 JavaScript 全局对象、函数以及变量均自动成为 window 对象的成员
