问题 I have an xml with utf8 encoding. And this file contains BOM a beginning of the file. So during parsing I am facing with org.xml.sax.SAXParseException: Content is not allowed in prolog. I can not remove those 3 bytes from the files. I can not load file into memory and remove them here (files are big). So for performance reasons I'm using SAX parser and want just to skip those 3 bytes if they are present before "" tag. Should I inherit InputStreamReader for this? I'm new in java - show me the

问题 I'm really confused with the codecs.open function . When I do: file = codecs.open("temp", "w", "utf-8") file.write(codecs.BOM_UTF8) file.close() It gives me the error UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128) If I do: file = open("temp", "w") file.write(codecs.BOM_UTF8) file.close() It works fine. Question is why does the first method fail? And how do I insert the bom? If the second method is the correct way of doing it, what the point

问题 The python code: sku_specs = "./item_specs.txt" def item_specs(): g = open(sku_specs,"r") lines = g.readlines() lines = "<br />".join(lines) return lines f = open("ouput.txt","a") f.write("Some stuff"+item_specs()+"more stuff") f.write("more stuff") f.close() The extra characters that show up even if the file is "blank" are  When I open the file in Notepad++ and "show all symobls" I still get these BOM characters when the .txt file appears to be blank.

问题 How would an awk script (presumably a one-liner) for removing a BOM look like? Specification: print every line after the first ( NR > 1 ) for the first line: If it starts with #FE #FF or #FF #FE , remove those and print the rest 回答1: Try this: awk 'NR==1{sub(/^\xef\xbb\xbf/,"")}{print}' INFILE > OUTFILE On the first record (line), remove the BOM characters. Print every record. Or slightly shorter, using the knowledge that the default action in awk is to print the record: awk 'NR==1{sub(/^\xef

问题 This question already has answers here : C++ reading from file puts three weird characters (3 answers) Closed 5 years ago . when I use the function readTheNRow with row=0 (i read the first row) i find that the three first chars are \357 ,\273 and \277. i found that this prefix is some how related to UTF-8 files, but some files have this prefix and some don't :( . how do i ignore all type of such prefixes in the files that i want to read from them? int readTheNRow(char buff[], int row) { int

问题 I accidentally checked in a utf8 encoded text file from Windows without removing the BOM before. Now I tried to remove it in a later version and check-in this change again. It seems as git ignores the change to the BOM bytes. Is there a setting to make git let me check-in the file like it is? (I know there is a similar issue when it comes to line endings - and there is a setting for this one...) 回答1: If you can make this reproducible, by all means report a bug Here's my two cents: xxd -r >

问题 There is a public webservice which I want to use in a short C# Application: http://ws.parlament.ch/ The returned XML from this webservice has a "BOM" at the beginning, which causes RESTSharp to fail the deserializing of the XML with the following error message: Error retrieving response. Check inner details for more info. ---> System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1. at System.Xml.XmlTextReaderImpl.Throw(Exception e) at System.Xml.XmlTextReaderImpl.Throw

问题 This question already has answers here : How to make Notepad to save text in UTF-8 without BOM? (7 answers) Closed last year . I want to read in a .txt file using ifstream fin from library fstream, but there is a BOM at the beginning of the file that is causing problems. Is there a way I can, from inside my C++ program, eliminate the BOM in the .txt file, so that fin can read it without any issues? I know I can manually delete the BOM in the file myself, but I have multiple files I'm working

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: “Warning: Headers already sent” in PHP When I create my php files with utf-8 bom, the header() function doesn't work because the bom chars are sent before the http headers. Does it mean that we shouldn't use bom in php source files? Is it a feature or bug? And what are your advices when working with utf-8 encoded php source files? 回答1: The BOM is useless in UTF-8. It's neither. PHP is working as intended. Your

问题 I have a file watcher that is grabbing content from a growing file encoded with utf-16LE. The first bit of data written to it has the BOM available -- I was using this to identify the encoding against UTF-8 (which MOST of my files coming in are encoded in). I catch the BOM and re-encode to UTF-8 so my parser doesn't freak out. The problem is that since it's a growing file not every bit of data has the BOM in it. Here's my question -- without prepending the BOM bytes to each set of data I have
