Index of CSS properties. W3C cheatsheet. The encoding used for an HTML page that contains a form should support all the characters needed to enter data into that form.
This is particularly important if users are likely to enter information in multiple languages. Databases and scripts that receive data from forms on pages in multiple languages must also be able to support the characters for all those languages simultaneously. The simplest way to enable this is to use Unicode for both pages containing forms and all back-end processing and storage. In such a scenario the user can fill in data in whatever language and script they need to.
You should also try to avoid making assumptions that things such as the user's name and address will follow the same formatting rules as your own. If you are gathering information from people in more than one country, it is important to develop a strategy for addressing the different formats people will expect to be able to use. So, how do I do this?

Getting started. HTML 4.01 Specification. Abstract This specification defines the HyperText Markup Language (HTML), the publishing language of the World Wide Web.
This specification defines HTML 4.01, which is a subversion of HTML 4. In addition to the text, multimedia, and hyperlink features of the previous versions of HTML (HTML 3.2 [HTML32] and HTML 2.0 [RFC1866]), HTML 4 supports more multimedia options, scripting languages, style sheets, better printing facilities, and documents that are more accessible to users with disabilities.
HTML 4 also takes great strides towards the internationalization of documents, with the goal of making the Web truly World Wide. HTML 4 is an SGML application conforming to International Standard ISO 8879 -- Standard Generalized Markup Language [ISO8879]. Status of this document This section describes the status of this document at the time of its publication. This document has been reviewed by W3C Members and other interested parties and has been endorsed by the Director as a W3C Recommendation.
