Web pages authored using hypertext markup language (HTML) may contain multilingual text represented with the Unicode universal character set. The relationship between Unicode and HTML tends to be a difficult topic for many computer professionals, document authors, and web users alike.
The accurate representation of text in web pages from different natural languages and writing systems is complicated by the details of character encoding, markup language syntax, font, and varying levels of support by web browsers.
Usually the best option is to enter characters as such, using a Unicode-capable authoring tool and saving and serving the document as UTF-8 encoded. This makes the HTML source more readable and avoids steps that might introduce errors.
