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 (€, ó, 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 BOM)
回答1:
You are probably not specifying the correct character set in your HTML file. The BOM (thanks @Jukka) sends the browser into UTF-.8 mode; in its absence, you need to use other means to declare the document UTF.8.
If you have access to your server configuration, you may want to make sure the server isn't sending the wrong character set info. See e.g. How to change the default encoding to UTF-8 for Apache?
If you have access only to your HTML, adding this meta tag in your document's head should do the trick:
<meta http-equiv='Content-Type' content='Type=text/html; charset=utf-8'>
or as @Mathias points out, the new HTML 5
<meta charset="utf-8">
(valid only if you use a HTML 5 doctype, against which there is no good argument any more even if you don't use HTML 5 markup.)
回答2:
Insert <meta charset="utf-8"> in head.
Or set the header Content-Type: text/html;charset=utf-8 on the server-side
You can also do add in .htaccess: AddDefaultCharset UTF-8 more info here http://www.askapache.com/htaccess/setting-charset-in-htaccess.html
