There is no default charset for HTML, and UTF-8 is not identical to ISO-8859-1. UTF-8 and ISO-8859-1 are only identical for the 7-bit (US-ASCII) characters. > You only > need to specify Windows 1252 if you are using non-Unicode Windows software > and have "hard-coded" characters such as euro sign, daggers, em dash, which > are where Latin-1 and Windows 1252 differ.

The charset declaration is required for HTML documents, regardless of whether you use entities. In practice, you're probably "safe" if you skip the charset and stick to US-ASCII, but there's no reason not to specify the charset. -- Liam Quinn
