Hexadecimal value 0x00 is a invalid character loading XML document

阅读更多关于 Hexadecimal value 0x00 is a invalid character loading XML document

问题 I recently had an XML which would not load. The error message was Hexadecimal value 0x00 is a invalid character received by the minimum of code in LinqPad (C# statements): var xmlDocument = new XmlDocument(); xmlDocument.Load(@"C:\Users\Thomas\AppData\Local\Temp\tmp485D.tmp"); I went through the XML with a hex editor but could not find a 0x00 character. I minimized the XML to <?xml version="1.0" encoding="UTF-8"?> <x> </x> In my hex editor it shows up as Offset(h) 00 01 02 03 04 05 06 07 08

问题 I've seen this post: ï»¿ characters appended to the begining of each file. In that case, the author was manually reading the source file and writing the contents. In my case, I'm abstracting it away via HttpRequest.TransmitFile(): public void ProcessRequest(HttpContext context) { HttpRequest req = context.Request; HttpResponse resp = context.Response; resp.ContentType = "application/javascript"; resp.TransmitFile("foo.js"); resp.TransmitFile("bar.js"); resp.TransmitFile("baz.js"); } The .js

Is it possible to prevent adding BOM to output UTF-8 file? (Visual Studio 2005)

阅读更多关于 Is it possible to prevent adding BOM to output UTF-8 file? (Visual Studio 2005)

问题 I need some help. I'm writing a program that opens 2 source files in UTF-8 encoding without BOM. The first contains English text and some other information, including ID. The second contains only string ID and translation. The program changes every string from the first file by replacing English chars to Russian translation from the second one and writes these strings to output file. Everything seems to be ok, but there is BOM appears in destination file. And i want to create file without BOM

问题 This code, OutputStream out = new FileOutputStream(new File("C:/file/test.txt")); out.write("A".getBytes()); And this, OutputStream out = new FileOutputStream(new File("C:/file/test.txt")); out.write("A".getBytes(StandardCharsets.UTF_8)); produce the same result(in my opinion), which is UTF-8 without BOM. However, Notepad++ is not showing any information about encoding . I'm expecting notepad++ to show here as Encode in UTF-8 without BOM , but no encoding is being selected in the "Encoding"

How to exclude BOM with BOM InputStream

阅读更多关于 How to exclude BOM with BOM InputStream

问题 I am trying to figure out how to simply exclude the BOM while using the example given by Apache. I am reading a file from Internal Storage and converting it first into a String . Then I convert it into ByteArray so that I get an InputStream . Then I check with BOMInputStream for BOMs, since I had errors for "Unexpected Tokens". Now I don't know how to exclude the BOM if I have it. CODE: StringBuffer fileContent = new StringBuffer(""); String temp = ""; int ch; try{ FileInputStream fis = ctx

How to convert PostgreSQL escape bytea to hex bytea?

阅读更多关于 How to convert PostgreSQL escape bytea to hex bytea?

问题 I got the answer to check for one certain BOM in a PostgreSQL text column. What I really like to do would be to have something more general, i.e. something like select decode(replace(textColumn, '\\', '\\\\'), 'escape') from tableXY; The result of a UTF8 BOM is: \357\273\277 Which is octal bytea and can be converted by switching the output of bytea in pgadmin: update pg_settings set setting = 'hex' WHERE name = 'bytea_output'; select '\357\273\277'::bytea The result is: \xefbbbf What I would

Why would I use a Unicode Signature Byte-Order-Mark (BOM)?

阅读更多关于 Why would I use a Unicode Signature Byte-Order-Mark (BOM)?

问题 Are these obsolete? They seem like the worst idea ever -- embed something in the contents of your file that no one can see, but impacts the file's functionality. I don't understand why I would want one. 回答1: They're necessary in some cases, yes, because there are both little-endian and big-endian implementations of UTF-16. When reading an unknown UTF-16 file, how can you tell which of the two is used? The only solution is to place some kind of easily identifiable marker in the file, which can

问题 I am using a Javascript file that is a concatenation of other JavaScript files. Unfortunately, the person who concatenated these JavaScript files together did not use the proper encoding when reading the file, and allowed a BOM for every single JavaScript file to get written to the concatenated JavaScript file. Does anyone know a simple way to search through the concatenated file and remove any/all BOM markers? Using PHP or a bash script for Mac OSX would be great. 回答1: See also: Using awk to
