Excel files with byte order mark for UTF-8 causing errors

阅读更多关于 Excel files with byte order mark for UTF-8 causing errors

问题 I am just wondering if there is any possible way to fix this. I receive Excel files at work that contain the splicing information for fibre joints, and when I try to import then I get an output error saying the first table didn't match up with what it expected to see. When I then open it, I can see the BOM for UTF-8 as ï»¿ directly before the word like this ï»¿Joint Name . Obviously this is hidden in the original file, and it causes a bit of manual work having to remove each of the symbols

BOM randomly appears in JSON reply

阅读更多关于 BOM randomly appears in JSON reply

问题 I'm implementing communication between two servers using JSON and cURL. The problem is, that sometimes there's BOM (byte order mark), appended before opening bracket in JSON reply. I've managed to trim it and successfully parse JSON string, but considering that JSON is generated by my own code, I've no idea, where does that BOM come from. I'm using json_encode() to generate reply and header() + echo to print it, an as far as I cant tell, json_decode() does not produce any BOMs. Corresponding

问题 I'm using an ajax request to send comments to DB. Succesful response is marked by 1. OK The problem actually is that the response from the php script is 1. 2. OK So I debugged the script and noted that the newline character si being added when the script executes the following line: require_once($ABS_APPS."/quotes/classQuote.php"); After some searches i read that it could be a BOM (Byte Order Mark) problem. So I just downloaded and opened the classQuote.php file with an hex editor and noticed

UTF-8 html without BOM displays strange characters

阅读更多关于 UTF-8 html without BOM displays strange characters

问题 I have some HTML which contains some forign characters (€, ó, á). The HTML document is saved as UTF-8 without BOM. When I view the page in the browser the forign characters seem to get replaced with stranger character combinations (â‚¬, Ã³, Ã). It's only when I save my HTML document as UTF-8 with BOM that the characters then display properly. I'd really rather not have to include a BOM in my files, but has anybody got any idea why it might do this? and a way to fix it? (other than including a

问题 I've got a site: http://www.sucramma.dk When I'm in FF, Chrome, or Safari, the site is displayed as it should, but in IE the site is left aligned, and is running is quirks mode. Why? The doctype is set! 回答1: It's a Byte Order Mark, , which is invisible to most text editors.

问题 I need suggestions on the way to remove BOM from an UTF-8 file and create a copy of the rest of the xml file. 回答1: Having a tool breaking because of a BOM in an UTF-8 file is a very common thing in my experience. I don't know why there where so many downvotes (but then it gives me the chance to try to get enough vote to win a special SO badge ; ) More seriously: an UTF-8 BOM doesn't typically make that much sense but it is fully valid (although discouraged) by the specs. Now the problem is
