Your website can be written in any language; we have no restrictions on what language you use. You can even use languages that require special character sets, like Chinese or Arabic.
In order for your web pages to display the correct character set for your language, you must be sure to specify this character set within your page. This is specified in the HEAD section of your HTML page with a line like the following:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
This line directs the web browser viewing the page to use the ISO-8859-1 character set, which is the standard latin character set. The most widely used and most compatible international character set is the 8-bit unicode character set called UTF-8.
Please note that if you do not specify a character set for your web page, the browser will use the native one for the language of the user; this means the page would not display correctly for users of other languages.
