Charset

[Smedzlatko]

w3.org document (http://www.w3.org/TR/html-markup/meta.charset.html) states this:

A case-insensitive match for any character set name for which the IANA [Character Sets] registry has a Name or Alias field labeled as “preferred MIME name”; or, if none of the Alias fields are so labeled, a case-insensitive match for a Name field in the registry.

Either way seems fine. As @Smedzlatko I think you'll only run into trouble with an XML page (like XHTML), per the linked spec:

For documents in the XML syntax, the value of the charset attribute must be a case-insensitive match for the string "UTF-8".

So, given we're HTML, and UTF is an abbreviation, we'll leave it as capitalized I guess.

@mdo I asked you about that because Bootstrap is using that way. :P

So, given we're HTML, and we write tags, attributes and the most of attribute values in the lower case, why shouldn't we write utf-8?

We are not writing this:

<META CHARSET="UTF-8">

😉

[mdo]

True, but when referencing it, it's UTF, not utf. I'll leave it as-is in the guide, but folks can do whatever they like. I don't care much either way for that kind of thing.

Okay.
