HTML/JavaScript
HTML and JavaScript applications.
base64 string encoder/decoder
The base64 string encoder/decoder encodes and decodes base64 strings. Unicode character values greater than 255 are supported through UTF-8 "character byte" encoding. The encoding library is written in JavaScript and available as a separate download.
mailto: builder/encoder
The mailto: builder/encoder creates mailto: links for HTML pages. The links are output in two formats: standard encoding and ISO 10646 encoding. The ISO 10646 encoding displays normally in web browsers, but can confuse programs that crawl web pages looking for email addresses to add to spam lists.
We've used mailto: builder/encoder to create all of the mailto: links on this site (and even the word "mailto:" anywhere you see it).
entity string encoder/decoder
The entity string encoder/decoder converts strings to and from their entity-encoded form, where each character is represented by its numeric (ISO 10646) value.
html to javascript converter
The html to javascript converter converts HTML source code to a series of Javascript statements.

This chart lists both HTML named entities (like & for ampersand) as well as ISO 10646 entity values (for the ampersand, this is &).
