Supports Unicode 4.0 and rewritten with Web Standards to work on a variety of browsers. - this is still work in progress and has some known bugs (esp surrogates), but I use it all the time.

Initially downloads about 1Mb of Unicode data, so you should use a fast connection. Once it's cached you're ok. Alternatively, download the newly available zip file and run it from your PC. It's just XHTML and Javascript - so no worries about viruses.

Pickers allow you to quickly create phrases in a script by clicking on Unicode characters arranged in a way that aids their identification. The phrase appears at the bottom of the screen and you can easily cut and paste the result into your own document. They're written in XHTML with a small amount of JavaScript.

Pickers are likely to be most useful if you don't know a script well enough to use the native keyboard. The arrangement of characters also makes it much more useable than a regular character map utility, and they may include characters from more than one block. New pickers are being added each week at the moment. Currently available pickers include (in French and English):

Arabic, Bengali, Devanagari, Hebrew, IPA, Malayalam, Thai, Tamil

This page helps you convert between characters, Unicode code point numbers, UTF-8 and UTF-16 code units in hex, and Numeric Character References (hex and decimal). Just add one type of data, press tab, and see all the corresponding values.

Now also available in French (thanks to François Yergeau).
