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.

Getting started. HTML 4.01 Specification. Abstract This specification defines the HyperText Markup Language (HTML), the publishing language of the World Wide Web.

HTML 4.01 Specification

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].
